3.0-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jean Delvare <kh...@linux-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.
