[PATCH] arm: drm: tegra: Set MODULE_FIRMWARE for the VIC

[PATCH] arm: drm: tegra: Set MODULE_FIRMWARE for the VIC

[Nicolas Chauvet]

The define is set anyway to prevent an empty string.
The test for the soc is same as nouveau for the tegra gpu firmware
(see drivers/gpu/drm/nouveau/nouveau_platform.c)

Fixes: 0ae797a8ba05 ("drm/tegra: Add VIC support")

I'd prefer to have the defines above each chip's vic_config struct 
definition, and the MODULE_FIRMWARE() part at the end of the file, like 
MODULE_* macros usually are. With that,

[PATCH] arm: drm: tegra: Set MODULE_FIRMWARE for the VIC

[Nicolas Chauvet]

The defines are set anyway to prevent an empty string.
The test for the soc is same as nouveau for the tegra gpu firmware
(see drivers/gpu/drm/nouveau/nouveau_platform.c)

Fixes: 0ae797a8ba05 ("drm/tegra: Add VIC support")

v2:
 - Place the defines above each chip's vic_config struct
 - MODULE_FIRMWARE() at the end of the file
