Subject: drivers/w1/slaves/w1_ds2781.c: fix the error handling in w1_ds2781_add_slave()
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=c28d6f2ddb10fd2b359083e89ae583c6c062e35f;p=openwrt%2Fstaging%2Fblogic.git

drivers/w1/slaves/w1_ds2781.c: fix the error handling in w1_ds2781_add_slave()

Use platform_device_put() instead of platform_device_unregister() if
platform_device_add() fail, and platform_device_del() should be used in
the error handling case after platform_device_add() success.
