Subject: spi: nxp-fspi: Use devm API to fix missed unregistration of controller
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=69c23dbf5f695c219008257b3bd86cff63edbe0b;p=openwrt%2Fstaging%2Fblogic.git

spi: nxp-fspi: Use devm API to fix missed unregistration of controller

This driver forgets to unregister controller when remove.
Use devm API to unregister it automatically to fix it.
