Subject: OMAP: DSS2: Taal: Fix DSI bus locking problem
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=6df37271f879f14119a0605549f1a2574e83b4fe;p=linux-beck.git

OMAP: DSS2: Taal: Fix DSI bus locking problem

If omapdss_dsi_display_enable() failed the DSI bus was left locked. Also
if the operation failed later omapdss_dsi_display_disable() would get
called without holding the bus lock.
