The null check on aconnector->base.edid_blob_ptr->data is redundant
since data is an array and can never be null.  Remove it.

[PATCH] drm/amd/display: remove redundant null check of array 'data'

2017-12-15 Thread Colin King 
From: Colin Ian King 

The null check on aconnector->base.edid_blob_ptr->data is redundant
since data is an array and can never be null.  Remove it.

Detected by CoverityScan, CID#1460369 ("Array compared against 0")
