drm/radeon: change function signature to pass full range
In function ‘radeon_process_i2c_ch’ a comparison of a u8 value against 255 is done. Since it is always false, change the signature of this function to use an `int` instead, which match the type used in caller: `radeon_atom_hw_i2c_xfer`. Fix the following warning triggered with W=1: CC [M] drivers/gpu/drm/radeon/atombios_i2c.o drivers/gpu/drm/radeon/atombios_i2c.c: In function ‘radeon_process_i2c_ch’: drivers/gpu/drm/radeon/atombios_i2c.c:71:11: warning: comparison is always false due to limited range of data type [-Wtype-limits] if (num > ATOM_MAX_HW_I2C_READ) { ^ Reviewed-by: Huang Rui <ray.huang@amd.com> Signed-off-by: Mathieu Malaterre <malat@debian.org> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
