[PATCH 1/2] drm/msm: add missing header dependencies

[PATCH 1/2] drm/msm: add missing header dependencies

[Baoyou Xie]

We get 2 warnings when building kernel with W=1:
drivers/gpu/drm/msm/msm_debugfs.c:141:5: warning: no previous prototype for 'msm_debugfs_init' [-Wmissing-prototypes]
drivers/gpu/drm/msm/msm_debugfs.c:158:6: warning: no previous prototype for 'msm_debugfs_cleanup' [-Wmissing-prototypes]

In fact, both functions are declared in drivers/gpu/drm/msm/msm_debugfs.h,
so this patch adds missing header dependencies.

[PATCH 2/2] drm/msm/adreno: move function declarations to header file

[Baoyou Xie]

We get 2 warnings when building kernel with W=1:
drivers/gpu/drm/msm/adreno/a3xx_gpu.c:535:17: warning: no previous prototype for 'a3xx_gpu_init' [-Wmissing-prototypes]
drivers/gpu/drm/msm/adreno/a4xx_gpu.c:624:17: warning: no previous prototype for 'a4xx_gpu_init' [-Wmissing-prototypes]

In fact, both functions are declared in
drivers/gpu/drm/msm/adreno/adreno_device.c, but should be declared in
a header file. So this patch moves both function declarations to
drivers/gpu/drm/msm/adreno/adreno_gpu.h.

Both patches

Reviewed-by: Arnd Bergmann <arnd@arndb.de>

Strangely, something caused the second mail to show up as a reply to the
first. No idea how that happened, but you may want to check the procedure
you used for sending the mails.

Both applied to drm-misc, thanks.

Not generated as a series, but individual patches, but then send out using
just 1 invocation of git send-email? "add" sorts before "adreno", and git
format-patch changes every non-alphanumeric character to a '-'.
