Subject: [PATCH 1/3] vidtv: psi: fix missing crc for PMT
Date: Thu, 24 Dec 2020 12:04:00 -0300 [thread overview]
Message-ID: <20201224150402.1945788-1-dwlsalmeida@gmail.com> (raw)
From: "Daniel W. S. Almeida" <dwlsalmeida@gmail.com>
The PMT write function was refactored and this broke the CRC computation.
Fix it.
Fixes: db9569f67e2e ("media: vidtv: cleanup PMT write table function")
