drm/amdgpu: use "*" adjacent to data name

2020-11-02T20:35:53+00:00

When declaring pointer data, the "*" symbol should be used adjacent to
the data name as per the coding standards. This resolves following
issues reported by checkpatch script:
	ERROR: "foo *   bar" should be "foo *bar"
	ERROR: "foo * bar" should be "foo *bar"
	ERROR: "foo*            bar" should be "foo *bar"
	ERROR: "(foo*)" should be "(foo *)"

drm/amdgpu: drm_device to amdgpu_device by inline-f (v2)

2020-08-24T17:06:06+00:00

Get the amdgpu_device from the DRM device by use
of an inline function, drm_to_adev(). The inline
function resolves a pointer to struct drm_device
to a pointer to struct amdgpu_device.

v2: Use a typed visible static inline function
    instead of an invisible macro.

drm/amdgpu: remove always false comparison in 'amdgpu_atombios_i2c_process_i2c_ch'

2019-11-13T20:29:44+00:00

Fixes gcc '-Wtype-limits' warning:

drivers/gpu/drm/amd/amdgpu/atombios_i2c.c: In function
‘amdgpu_atombios_i2c_process_i2c_ch’:
drivers/gpu/drm/amd/amdgpu/atombios_i2c.c:79:11: warning: comparison is
always false due to limited range of data type [-Wtype-limits]

'num' is 'u8', so it will never be greater than 'TOM_MAX_HW_I2C_READ',
which is defined as 255. Therefore, the comparison can be removed.

drm/amdgpu: add missing header dependencies

2016-09-14T19:10:37+00:00

We get a few warnings when building kernel with W=1:
drivers/gpu/drm/amd/amdgpu/amdgpu_pll.c:113:6: warning: no previous prototype for 'amdgpu_pll_compute' [-Wmissing-prototypes]
drivers/gpu/drm/amd/amdgpu/cz_smc.c:38:10: warning: no previous prototype for 'cz_get_argument' [-Wmissing-prototypes]
drivers/gpu/drm/amd/amdgpu/cz_smc.c:302:5: warning: no previous prototype for 'cz_smu_start' [-Wmissing-prototypes]
....

In fact, these functions are declared in
drivers/gpu/drm/amd/amdgpu/atombios_i2c.h
drivers/gpu/drm/amd/amdgpu/amdgpu_pll.h
drivers/gpu/drm/amd/amdgpu/cz_dpm.h
drivers/gpu/drm/amd/amdgpu/vi_dpm.h.
So this patch adds missing header dependencies.
