Subject: [PATCH 1/3] staging: vt6656: Use ARRAY_SIZE instead of define RATE_54M
Date: Sat, 4 Apr 2020 16:13:58 +0200 [thread overview]
Message-ID: <20200404141400.3772-2-oscar.carter@gmx.com> (raw)
In-Reply-To: <20200404141400.3772-1-oscar.carter@gmx.com>
Use ARRAY_SIZE to replace the define RATE_54M so we will never have a
mismatch. In this way, avoid the possibility of a buffer overflow if
this define is changed in the future to a greater value.
