From fcef677bdaaab23fa2ebe446d1fa5cd77d908858 Mon Sep 17 00:00:00 2001 From: Sree Sesha Aravind Vadrevu Date: Tue, 1 Jul 2014 14:44:11 -0700 Subject: msm: mdss: modify userspace src format during MSMFB_SET on rotator The req->src.format field should be changed to the destination format and propagated to the user so that appropriate buffer size calculations for the destination buffer can be made. Note, this only changes the user copy and the driver fetches the source buffer based on source format.
