From: Wolfram Sang Date: Sun, 29 Apr 2018 18:41:04 +0000 (+0200) Subject: i2c: busses: remove superfluous ignoring of children for RPM X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=77bade677c3c5616dfadfd21f0220fcddbfa4cbe;p=linux.git i2c: busses: remove superfluous ignoring of children for RPM These days, the I2C core ensures that the embedded adapter device ignores the PM states of its children already. Because the adapter device is an opaque logical device, there is no need for drivers to repeat that again.
