[PATCH v2] drm/msm: use BUG_ON macro for debugging.

From: Wambui Karuga
Date: Thu Jan 09 2020 - 04:42:37 EST


As the if statement only checks for the value of the offset_name
variable, it can be replaced by the more conscise BUG_ON macro for error
reporting.

v2: format expression to less than 80 characters for each line.
