[PATCH] staging: r8188eu: remove kernel version depended code paths

From: Michael Straube
Date: Sun Aug 15 2021 - 06:25:17 EST


Remove kernel version depended code paths from the driver.
Reported by checkpatch.

WARNING: LINUX_VERSION_CODE should be avoided, code should be for the version to which it is merged
