Subject: [PATCH 07/11] wil6210: update cid boundary check of wil_find_cid/_by_idx()
Date: Sun, 16 Jun 2019 10:26:03 +0300
Message-ID: <1560669967-23706-8-git-send-email-merez@codeaurora.org> (raw)
In-Reply-To: <1560669967-23706-1-git-send-email-merez@codeaurora.org>

From: Alexei Avshalom Lazar <ailizaro@codeaurora.org>

The return value of wil_find_cid()/wil_find_cid_by_idx() is
validated with the lower boundary value.
Check the upper boundary value as well.
