Message-Id: <1355407206-17100-55-git-send-email-herton.krzesinski@canonical.com> Date: Thu, 13 Dec 2012 11:56:59 -0200 From: Herton Ronaldo Krzesinski <herton.krzesinski@...onical.com> To: linux-kernel@...r.kernel.org, stable@...r.kernel.org, kernel-team@...ts.ubuntu.com Cc: Jean Delvare <khali@...ux-fr.org>, Herton Ronaldo Krzesinski <herton.krzesinski@...onical.com> Subject: [PATCH 054/241] hwmon: (w83627ehf) Force initial bank selection 3.5.7.2 -stable review patch. If anyone has any objections, please let me know. ------------------ From: Jean Delvare <khali@...ux-fr.org> commit 3300fb4f88688029fff8dfb9ec0734f6e4cba3e7 upstream. Don't assume bank 0 is selected at device probe time. This may not be the case. Force bank selection at first register access to guarantee that we read the right registers upon driver loading.
