Subject: nvdimm: Remove empty if statement
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=19418b024427ec60ba6084addf691a8d93670398;p=openwrt%2Fstaging%2Fblogic.git

nvdimm: Remove empty if statement

This patch removes an empty statement from an if expression and promotes
the else statement to the if expression with the expression logic reversed.

I feel this is more readable as the empty statement can lead to issues if
any additional logic was ever added.
