Subject: [PATCH AUTOSEL 5.7 276/388] mfd: wcd934x: Drop kfree for memory allocated with devm_kzalloc

From: Wei Yongjun <weiyongjun1@...wei.com>

[ Upstream commit 652b7b6740eb52d98377a881c7730e36997f00ab ]

It's not necessary to free memory allocated with devm_kzalloc
and using kfree leads to a double free.

Fixes: 6ac7e4d7ad70 ("mfd: wcd934x: Add support to wcd9340/wcd9341 codec")
