Subject: linux-next: manual merge of the thermal-soc tree with Linus' tree
Date: Wed, 15 May 2019 10:05:12 +1000 [thread overview]
Message-ID: <20190515100512.24b80412@canb.auug.org.au> (raw)
[-- Attachment #1: Type: text/plain, Size: 5120 bytes --]
Hi all,
Today's linux-next merge of the thermal-soc tree got a conflict in:
drivers/hwmon/pwm-fan.c
between commits:
6b1ec4789fb1 ("hwmon: (pwm-fan) Add RPM support via external interrupt")
841cf6767bf6 ("hwmon: (pwm-fan) Report probe errors consistently")
from Linus' tree and commit:
37bcec5d9f71 ("hwmon: (pwm-fan) Use devm_thermal_of_cooling_device_register")
from the thermal-soc tree.
I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging. You may also want to consider cooperating
with the maintainer of the conflicting tree to minimise any particularly
complex conflicts.

Cheers,
Stephen Rothwell
