Subject: PM / Hibernate: Replace unintuitive 'if' condition in kernel/power/user.c with 'else'
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=e5b16746f0f2d6883c226af52d90904ce0f7eee8;p=openwrt%2Fstaging%2Fblogic.git

PM / Hibernate: Replace unintuitive 'if' condition in kernel/power/user.c with 'else'

In the snapshot_ioctl() function, under SNAPSHOT_FREEZE, the code below
freeze_processes() is a bit unintuitive. Improve it by replacing the
second 'if' condition with an 'else' clause.
