Subject: drm/atomic-helper: Use bitwise or for filling a bitmask
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=ca52bea9fa8007f837ab4685b98979bbffc33416;p=openwrt%2Fstaging%2Fblogic.git

drm/atomic-helper: Use bitwise or for filling a bitmask

Using += to set the bits in a mask looks funny. It works in this case
because we never set the same bit twice. But let's switch to |= to
make this look more regular.
