With the introduction of runtime power management in commit 2db5054ac2
("staging: iio: isl29028: add runtime power management support"), the
system could go to sleep and turn off the device without notifying the
runtime power management code. This patch changes the system suspend
and resume to go through the runtime power management.

When proximity is enabled in isl29028_enable_proximity(), the function
msleep() is called with the sampling frequency, which is not correct.
This patch changes the code to sleep the specified amount of time listed
in the datasheet instead.

This driver in some cases can busy wait for upwards of 100 ms. Since the
kernel at this point is not running in atomic context, and is running in
process context, we can safely use msleep() instead. This patch changes
the two occurrences of mdelay() to msleep().

MAX30102 is an heart rate and pulse oximeter sensor that works using
two LEDS of different wavelengths, and detecting the light reflected
back.
This patchset adds support for both IR and RED LED channels which can
be processed in userspace to determine heart rate and blood oxygen
levels. The MAX30102 part isn't completely register and functional
compatible with the existing MAX30100 driver.

This patch adds support for the ultrasonic ranger srf04 of devantech.
This device is measuring the distance of objects in a range between 1 cm
and 3 meters and a theoretical resolution of 3 mm.
There are two GPIOs used:
- trigger: set as output to the device when the measurement should start
- echo: set by the device when the ultrasonic wave is sent out and reset
when the echo is recognized; this needs to be an interrupt input
The time between setting and resetting the echo pin is the time the
waveform needed for one round trip. This time is recorded in the interrupt
handler.
The distance is calculated in the read function by using the ultrasonic
speed at 20 degrees celsius which is about 343 m/s.

This patch makes no functional changes. Struct initializers in the
fid directory that use C89 or GCC-only syntax are updated to C99
syntax.
The C99 syntax prevents incorrect initialization if values are
accidently placed in the wrong position, allows changes in the struct
definition, and clears any members that are not given an explicit
value.
The following struct initializers have been updated:
lustre/fid/fid_lib.c:
const struct lu_seq_range LUSTRE_SEQ_SPACE_RANGE
const struct lu_seq_range LUSTRE_SEQ_ZERO_RANGE
lustre/fid/lproc_fid.c:
struct lprocfs_vars seq_client_debugfs_list

The replay cursor should be updated properly when close happened
during replay, otherwise, ptlrpc_replay_next() could run into a
dead loop due to an invalid replay cursor:
- replay cursor is moved to an open request during replay;
- application close that open file, so the rq_replay of the open
request is cleared;
- ptlrpc_replay_next() calls ptlrpc_free_committed() to free
committed/closed requests, the open request is removed from
the committed list, so the replay cursor is changed to an
empty list_head now. The open request won't be freed now since
it's still held by the pending close request;
- ptlrpc_replay_next() continue to move the replay cursor to
next and run into a dead loop at the end;
Another change in this patch is to remove the out of date comments
in ptlrpc_replay_next() and cover the whole process of finding
replay request within imp_lock, because:
1. With two separated replay lists and replay cursor introduced,
finding replay request won't take much time as before, it's
not necessary to do this "lock -> unlock -> lock -> unlock"
trick anymore;
2. Nowadays there are various kind of non-replay requests are
allowed during recovery, so ptlrpc_free_committed() may run in
parallel to remove an open request while ptlrpc_replay_next()
is iterating the open requests list;

The patch updates the prototype in osc_internal.h to match the
enums used in the declaration.
The osc_match_base declaration in lustre/osc/osc_request.c uses
enums for stricter checking on the type and mode parameters:
int osc_match_base(struct obd_export *exp,
...
--> enum ldlm_type type,
union ldlm_policy_data *policy,
--> enum ldlm_mode mode,
... int unref)
The prototype in lustre/osc/osc_internal.h instead used unsigned ints:
int osc_match_base(struct obd_export *exp,
...
--> __u32 type,
union ldlm_policy_data *policy,
--> __u32 mode,

reply_out_callback() should call ptlrpc_schedule_difficult_reply()
to finalize the rs if it's already not on uncommitted list, otherwise,
the rs and the export held by rs could be leaked:
- target_send_reply() sends a difficult reply before the transaction
committed, the reply is linked to scp_rep_active;
- export gets disconnected by umount or whatever reason,
server_disconnect_export() is called to complete all outstanding
replies, which will calls into ptlrpc_handle_rs() to dispose of
the rs, so the rs is removed from the uncommitted list and
LNetMDUnlink() is called to unlink the reply buffer and generate
an unlink event;
- reply_out_callback() is called to process above unlink event,
ptlrpc_schedule_difficult_reply() is supposed to be called to
dispose of the rs finally. However, it could be skipped because of
following flawed code snippet:
if (!rs->rs_no_ack ||
rs->rs_transno <= rs->rs_export->exp_obd->obd_last_committed)
ptlrpc_schedule_difficult_reply(rs);
The intention of above code is: if rs_no_ack is true (COS enabled),
and transaction is not committed, we should rely on commit callback
to release the rs. However, it overlooked the situation that rs
could have been removed from the uncommitted list by disconnecting
export.
