Subject: [PATCH] ath6kl: minor fix for allocation size
Date: Tue, 17 Jan 2023 14:04:14 +0300	[thread overview]
Message-ID: <20230117110414.GC12547@altlinux.org> (raw)

[-- Attachment #1: Type: text/plain, Size: 1026 bytes --]

Although the "param" pointer occupies more or equal space compared
to "*param", the allocation size should use the size of variable
itself.

Found by Linux Verification Center (linuxtesting.org) with SVACE.

Fixes: bdcd81707973cf8a ("Add ath6kl cleaned up driver")
Signed-off-by: Alexey V. Vissarionov <gremlin@altlinux.org>
