Subject: [PATCH] thermal: fix thermal_cooling_device_register() prototype
Date: Thu, 22 Jul 2021 11:06:44 +0200 [thread overview]
Message-ID: <20210722090717.1116748-1-arnd@kernel.org> (raw)
From: Arnd Bergmann <arnd@arndb.de>
There are two pairs of declarations for thermal_cooling_device_register()
and thermal_of_cooling_device_register(), and only one set was changed
in a recent patch, so the other one now causes a compile-time warning:
drivers/net/wireless/mediatek/mt76/mt7915/init.c: In function 'mt7915_thermal_init':
drivers/net/wireless/mediatek/mt76/mt7915/init.c:134:48: error: passing argument 1 of 'thermal_cooling_device_register' discards 'const' qualifier from pointer target type [-Werror=discarded-qualifiers]
134 | cdev = thermal_cooling_device_register(wiphy_name(wiphy), phy,
| ^~~~~~~~~~~~~~~~~
In file included from drivers/net/wireless/mediatek/mt76/mt7915/init.c:7:
include/linux/thermal.h:407:39: note: expected 'char *' but argument is of type 'const char *'
407 | thermal_cooling_device_register(char *type, void *devdata,
| ~~~~~~^~~~
Change the dummy helper functions to have the same arguments as the
normal version.
Fixes: f991de53a8ab ("thermal: make device_register's type argument const")
