Subject: [PATCH] pinctrl: sprd: Use define directive for sprd_pinconf_params values
Date: Wed, 31 Oct 2018 17:44:10 -0700 [thread overview]
Message-ID: <20181101004410.6893-1-natechancellor@gmail.com> (raw)
Clang warns when one enumerated type is implicitly converted to another:
drivers/pinctrl/sprd/pinctrl-sprd.c:845:19: warning: implicit conversion
from enumeration type 'enum sprd_pinconf_params' to different
enumeration type 'enum pin_config_param' [-Wenum-conversion]
{"sprd,control", SPRD_PIN_CONFIG_CONTROL, 0},
~ ^~~~~~~~~~~~~~~~~~~~~~~
drivers/pinctrl/sprd/pinctrl-sprd.c:846:22: warning: implicit conversion
from enumeration type 'enum sprd_pinconf_params' to different
enumeration type 'enum pin_config_param' [-Wenum-conversion]
{"sprd,sleep-mode", SPRD_PIN_CONFIG_SLEEP_MODE, 0},
~ ^~~~~~~~~~~~~~~~~~~~~~~~~~
It is expected that pinctrl drivers can extend pin_config_param because
of the gap between PIN_CONFIG_END and PIN_CONFIG_MAX so this conversion
isn't an issue. Most drivers that take advantage of this define the
PIN_CONFIG variables as constants, rather than enumerated values. Do the
same thing here so that Clang no longer warns.
