Subject: drm/i915: put back the indent in intel_hpd_irq_handler
X-Git-Tag: v4.3-rc1~75^2~36^2~314
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=ab68d5bb0b49727e4049b018185f82764cf44736;p=karo-tx-linux.git

drm/i915: put back the indent in intel_hpd_irq_handler

In an unfortunate back and forth stepping, retract the earlier change to
reduce indent. This is to make merging the two loops easier. No
functional changes.
