Logging messages that show some type of "out of memory" error
are generally unnecessary as there is a generic message and
a stack dump done by the memory subsystem.
These messages generally increase kernel size without much
added value.

These are similar macros so use the normal kernel one.
As well, there are odd games being played with casting a plist to

Functions rtl_rfreg_delay() and rtl_bb_delay() are unused within the

The resource release on probe/init error was being handled

It is recommended to use managed function devm_request_irq(),
which simplifies driver cleanup paths and driver code.
This patch does the following:
(a) replace platform_get_resource(), request_irq() and corresponding
error handling with platform_get_irq() and devm_request_irq().
(b) remove struct resource pointer(res_irq) in struct ssi_drvdata as
it seems redundant.
(c) change type of member irq in struct ssi_drvdata from unsigned int
to int, as return type of platform_get_irq is int and can be used in
error handling.
(d) remove irq_registered variable from driver probe as it seems
redundant.
(e) free_irq is not required any more, devm_request_irq() free's it
on driver detach.
(f) adjust log messages accordingly and remove any blank lines.

This patch does the following:
(a) replace request_mem_region(), ioremap() and corresponding error

(b) remove struct resource pointer(res_mem) in struct ssi_drvdata as it
seems redundant, use struct resource pointer which is defined locally and
adjust return value of platform_get_resource() accordingly.
(c) release_mem_region() and iounmap() are dropped, since devm_ioremap_
resource() releases and unmaps mem region on driver detach.

It is recommended to use managed function devm_kzalloc, which
simplifies driver cleanup paths and driver code.
This patch does the following:
(a) replace kzalloc with devm_kzalloc.
(b) drop kfree(), because memory allocated with devm_kzalloc() is
automatically freed on driver detach, otherwise it leads to a double
free.
(c) remove unnecessary blank lines.

As gcc-8 points out, the bit mask check makes no sense here:
drivers/staging/rts5208/sd.c: In function 'ext_sd_send_cmd_get_rsp':
drivers/staging/rts5208/sd.c:4130:25: error: bitwise comparison always evaluates to true [-Werror=tautological-compare]
However, the code is even more bogus, as we have already
checked for the SD_RSP_TYPE_R0 case earlier in the function
and returned success. As seen in the mmc/sd driver core,
SD_RSP_TYPE_R0 means "no response" anyway, so checking for
a particular response would not help either.
This just removes the nonsensical code to get rid of the
warning.

Commit 5620a0d1aa ("firmware: delete in-kernel firmware") removed the
entire firmware directory. Unfortunately it thereby also removed the
support for built-in firmware.
This restores the ability to build firmware directly into the kernel by
pruning the original Makefile to the necessary minimum. The default for
EXTRA_FIRMWARE_DIR is now the standard directory /lib/firmware/.

The driver doesn't support events from address families other than IPv4
and IPv6, so ignore them. Otherwise, we risk queueing a work item before
it's initialized.
This can happen in case a VRF is configured when MROUTE_MULTIPLE_TABLES
is enabled, as the VRF driver will try to add an l3mdev rule for the
IPMR family.
