Subject: Remove MAYBE_BUILD_BUG_ON
X-Git-Tag: firefly_0821_release~7613^2~2606^2
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=1765e3a4933ea0870fabd755feffc5473c4363ce;p=firefly-linux-kernel-4.4.55.git

Remove MAYBE_BUILD_BUG_ON

Now BUILD_BUG_ON() can handle optimizable constants, we don't need
MAYBE_BUILD_BUG_ON any more.
