Subject: firmware_class: fix typo in error path
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f45f3c1f3f616ca1d1e1eb5e7a720ca63cb59550;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

firmware_class: fix typo in error path

In the error path, _request_firmware sets
firmware_p to NULL rather than *firmware_p,
which leads to passing a freed firmware
struct to drivers when the firmware file
cannot be found. Fix this.

Broken by commit f8a4bd3456b988fc73b2c.
