Subject: wireless, libertas: remove redundant NULL tests before calling release_firmware()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a7b957a277215da1830596c0791307a999fe5153;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

wireless, libertas: remove redundant NULL tests before calling release_firmware()

release_firmware() tests for, and deals gracefully with, NULL
pointers. Remove redundant explicit tests before calling the function.
