Message-Id: <20210802192721.23110-2-Larry.Finger@lwfinger.net>
Date: Mon, 2 Aug 2021 14:27:16 -0500
From: Larry Finger <Larry.Finger@...inger.net>

Subject: [PATCH v2 1/6] staging: r8188eu: Remove wrappers for kalloc() and kzalloc()
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@...inger.net>
---
v2 - removed the extraneous files that were inadvertently added in v1
