Subject: OMAP: DSS2: Fix error path in omap_dsi_update()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=e9c31afcffe3df90ebac343611b2f0177bf3cbe4;p=linux-beck.git

OMAP: DSS2: Fix error path in omap_dsi_update()

In the case of an error on calling dsi_update_screen_l4(), a
successful framedone callback is still sent to panel-taal. An
error should be returned to taal_update() instead.
