drivers/staging: make android ashmem.c explicitly non-modular

2015-10-13T04:12:17+00:00

The Kconfig currently controlling compilation of this code is:

drivers/staging/android/Kconfig:config ASHMEM
drivers/staging/android/Kconfig:        bool "Enable the Anonymous Shared Memory Subsystem"

...meaning that it currently is not being built as a module by anyone.

Lets remove the modular code that is essentially orphaned, so that
when reading the driver there is no doubt it is builtin-only.

Since module_init translates to device_initcall in the non-modular
case, the init ordering remains unchanged with this commit.

We replace module.h with init.h and export.h ; the latter since this
file uses the global THIS_MODULE.

We also delete the MODULE_LICENSE tag etc. since all that information
is already contained at the top of the file in the comments.

Staging: android: Remove unnecessary braces.

2015-09-13T01:24:53+00:00

The linux kernel coding style discourages use of braces for single
statement blocks. This patch removes the unnecessary braces.

The warning was detected using checkpatch.pl. Coccinelle was used
to make the change.

Merge tag 'staging-4.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging

2015-08-31T16:24:06+00:00

Pull staging driver updates from Greg KH:
 "Here is the big staging driver updates for 4.3-rc1.

  Lots of things all over the place, almost all of them trivial fixups
  and changes.  The usual IIO updates and new drivers and we have added
  the MOST driver subsystem which is getting cleaned up in the tree.
  The ozwpan driver is finally being deleted as it is obviously
  abandoned and no one cares about it.

  Full details are in the shortlog, and all of these have been in
  linux-next with no reported issues"

char: make misc_deregister a void function

2015-08-05T17:35:49+00:00

With well over 200+ users of this api, there are a mere 12 users that
actually checked the return value of this function.  And all of them
really didn't do anything with that information as the system or module
was shutting down no matter what.

So stop pretending like it matters, and just return void from
misc_deregister().  If something goes wrong in the call, you will get a
WARNING splat in the syslog so you know how to fix up your driver.
Other than that, there's nothing that can go wrong.

drivers: staging: Drop unlikely before IS_ERR(_OR_NULL)

2015-07-31T23:18:43+00:00

IS_ERR(_OR_NULL) already contain an 'unlikely' compiler flag and there
is no need to do that again from its callers. Drop it.

This also replaces an IS_ERR(x) + (x == NULL) check to IS_ERR_OR_NULL
check.
