Subject: mtd: delete unnecessary checks before two function calls
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=05a221bb1f49e6eebc9a3858cb45506f403b3ab6;p=openwrt%2Fstaging%2Fblogic.git

mtd: delete unnecessary checks before two function calls

The functions kfree() and pci_dev_put() test whether their argument is NULL
and then return immediately. Thus the test around the call is not needed.

This issue was detected by using the Coccinelle software.
