Subject: [PATCH] drm/msm/dp: Remove redundant initialization of variable bpp

From: Colin Ian King <colin.king@...onical.com>

The variable bpp is being initialized with a value that is never
read, it is being updated later on in both paths of an if statement.
The assignment is redundant and can be removed.

Addresses-Coverity: ("Unused value")
