Subject: w1: w1-gpio: claim the gpio with correct initial flag
X-Git-Tag: v2021.10-rc1~36^2~1
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=dffea443a3c4d899085f7c0d307dbb8e88ea849a;p=pandora-u-boot.git

w1: w1-gpio: claim the gpio with correct initial flag

gpio_request_by_name should be called with proper flags.
The 0 value flag is invalid, and causes bad initialization of the gpio.
