returned value of lnet_post_send_locked and
lnet_post_routed_recv_locked are changed to -ve by:
http://review.whamcloud.com/#/c/9369/
this is wrong because callers rely on +ve to identify blocked
message which is not a failure.
To respect linux kernel coding style and not use positive error
code, this patch adds two macros as non-error returned values of
these functions:
LNET_CREDIT_OK has credit for message
LNET_CREDIT_WAIT no credit and message is blocked
both these functions will return these two values instead of 0
and EAGAIN

Remove most uses of IS_ERR_VALUE(). This macro was often given an int
argument coming from PTR_ERR(). This invokes implementation defined
behavior since the long value gotten by applying PTR_ERR() to a kernel
pointer will usually not be representable as an int. Moreover it may
be just plain wrong to do this since the expressions IS_ERR(p) and
IS_ERR_VALUE((int) PTR_ERR(p)) are not equivalent for a general
pointer p.

This patch gets rid of struct typedefs wilc_cfg_byte_t, wilc_cfg_hword_t,
wilc_cfg_word_t and wilc_cfg_str_t as as linux kernel coding style
guidelines suggest not using typdefs for structure types.
Also drop '_t' from the names.

This change has been made with the goal that kernel functions should
return something more descriptive than -1 on failure.
The return value on an alloc_etherdev failure should be -ENOMEM,
and not -1.
This was found using Coccinelle. A simplified version of the semantic
patch used is:
//<smpl>
@@
expression *e;
identifier l1;
@@
e = alloc_etherdev(...);
if (e == NULL) {
...
return
- -1
+ -ENOMEM
;
}
//</smpl
Furthermore, introduced `ret` variable to store and return the
corresponding error code returned by register_netdev on failure.
The two call sites store the return value in a variable which only
checks that the value is non-zero, hence no change is required at
the call sites.

This driver uses functionality (MSI IRQ domain) whose symbols aren't
exported, and hence the modular build fails. While arguably there might
be reasons to make these symbols available to modules, that change would
be fairly involved and the set of exported functions should be carefully
auditioned. Fix the build failure for now by marking the driver boolean.
