Bich Hemon bfbaf631bd drm/sti: awg_utils code cleanup
data_en is a local variable that doesn't need to be set as
awg_generate_instr can be called directly with the requested value.

Rasmus Villemoes cebd6fbeb2 drm/sti: remove redundant sign extensions
arg is long int, so arg = (arg << 22) >> 22 makes the upper 22 bits of
arg equal to bit 9 (or bit 41). But we then mask away all but bits 0-9, so
this is entirely redundant.

The shift and the mask done on arg value is useless
since arg is null.
