[PATCH v2 1/6] staging: r8188eu: Remove wrappers for kalloc() and kzalloc()

From: Larry Finger
Date: Mon Aug 02 2021 - 15:27:39 EST

These wrappers involve an in_interrupt() call, which is not frowned on
in the kernel. These changes decrease the size of the driver by a trivial
amount.

Signed-off-by: Larry Finger <Larry.Finger@xxxxxxxxxxxx>
---
v2 - removed the extraneous files that were inadvertently added in v1
