Subject: [PATCH 4.9 21/32] ASoC: jz4740-i2s: Fix divider written at incorrect offset in register

From: Paul Cercueil <paul@...pouillou.net>

commit 9401d5aa328e64617d87abd59af1c91cace4c3e4 upstream.

The 4-bit divider value was written at offset 8, while the jz4740
programming manual locates it at offset 0.

Fixes: 26b0aad80a86 ("ASoC: jz4740: Add dynamic sampling rate support to jz4740-i2s")
