3.13.11-ckt24 -stable review patch. If anyone has any objections, please let
me know.
------------------
From: Axel Lin <axel....@ingics.com>
commit 14ba3ec1de043260cecd9e828ea2e3a0ad302893 upstream.
According to the datasheet:
R10 (0Ah) VMID Impedance Control
BIT 3:2 VMIDSEL DEFAULT 00
DESCRIPTION: VMID impedance selection control
00: 75kΩ output
01: 300kΩ output
10: 2.5kΩ output
WM8737_VMIDSEL_MASK is 0xC (VMIDSEL - [3:2]),
so it needs to left shift WM8737_VMIDSEL_SHIFT bits for setting these bits.
