From 1cf79db28ef53aeaa66a825e8f788d19fdd8648f Mon Sep 17 00:00:00 2001 From: Peter Rosin Date: Wed, 4 May 2016 22:15:33 +0200 Subject: [media] rtl2832: change the i2c gate to be mux-locked The root i2c adapter lock is then no longer held by the i2c mux during accesses behind the i2c gate, and such accesses need to take that lock just like any other ordinary i2c accesses do. So, declare the i2c gate mux-locked, and zap the regmap overrides that makes the i2c accesses unlocked and use plain old regmap accesses. This also removes the need for the regmap wrappers used by rtl2832_sdr, so deconvolute the code further and provide the regmap handle directly instead of the wrapper functions.
