Subject: [PATCH 01/10] staging: r8188eu: Remove wrappers for kalloc() and kzalloc()
Date: Tue,  3 Aug 2021 08:52:14 -0500	[thread overview]
Message-ID: <20210803135223.12543-2-Larry.Finger@lwfinger.net> (raw)
In-Reply-To: <20210803135223.12543-1-Larry.Finger@lwfinger.net>

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.
