From 17eb1881f011f31148b32ab91fc4052737168084 Mon Sep 17 00:00:00 2001 From: Stephan Gerhold Date: Wed, 13 Oct 2021 16:32:30 +0800 Subject: [PATCH] extcon: sm5502: Drop invalid register write in sm5502_reg_data stable inclusion from stable-5.10.50 commit e16fcc83748a25107dd2deb047b1db2aa6420fdf bugzilla: 174522 https://gitee.com/openeuler/kernel/issues/I4DNFY Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=e16fcc83748a25107dd2deb047b1db2aa6420fdf -------------------------------- [ Upstream commit d25b224f8e5507879b36a769a6d1324cf163466c ] When sm5502_init_dev_type() iterates over sm5502_reg_data to initialize the registers it is limited by ARRAY_SIZE(sm5502_reg_data). There is no need to add another empty element to sm5502_reg_data. Having the additional empty element in sm5502_reg_data will just result in writing 0xff to register 0x00, which does not really make sense.
