From d48f8a6f4a204d679819d6147e9933695f3bee32 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Fri, 6 Oct 2023 23:04:18 +0200 Subject: [PATCH] pinctrl: realtek: Tag unused pins as __maybe_unused These pin definitions are helpful to have when working with the driver in the future, so they are in a sense a bit like documentation. They could be commented out as well, but why. This should fix these build warnings: drivers/pinctrl/realtek/pinctrl-rtd1315e.c:231:35: warning: 'rtd1315e_boot_sel_pins' defined but not used [-Wunused-const-variable=] drivers/pinctrl/realtek/pinctrl-rtd1315e.c:231:35: warning: 'rtd1315e_reset_n_pins' defined but not used [-Wunused-const-variable=] drivers/pinctrl/realtek/pinctrl-rtd1315e.c:231:35: warning: 'rtd1315e_scan_switch_pins' defined but not used [-Wunused-const-variable=] drivers/pinctrl/realtek/pinctrl-rtd1315e.c:231:35: warning: 'rtd1315e_testmode_pins' defined but not used [-Wunused-const-variable=] drivers/pinctrl/realtek/pinctrl-rtd1315e.c:231:35: warning: 'rtd1315e_wd_rset_pins' defined but not used [-Wunused-const-variable=] drivers/pinctrl/realtek/pinctrl-rtd1319d.c:237:35: warning: 'rtd1319d_boot_sel_pins' defined but not used [-Wunused-const-variable=] drivers/pinctrl/realtek/pinctrl-rtd1319d.c:237:35: warning: 'rtd1319d_reset_n_pins' defined but not used [-Wunused-const-variable=] drivers/pinctrl/realtek/pinctrl-rtd1319d.c:237:35: warning: 'rtd1319d_scan_switch_pins' defined but not used [-Wunused-const-variable=] drivers/pinctrl/realtek/pinctrl-rtd1319d.c:237:35: warning: 'rtd1319d_testmode_pins' defined but not used [-Wunused-const-variable=] drivers/pinctrl/realtek/pinctrl-rtd1319d.c:237:35: warning: 'rtd1319d_wd_rset_pins' defined but not used [-Wunused-const-variable=] Cc: Tzuyi Chang Link: https://lore.kernel.org/oe-kbuild-all/202309270313.mBEc9o1A-lkp@intel.com/ Link: https://lore.kernel.org/oe-kbuild-all/202309270448.7Aen3Sgx-lkp@intel.com/ Signed-off-by: Linus Walleij Link: https://lore.kernel.org/r/20231006-fix-realtek-warnings-v1-1-09af253312ba@linaro.org --- drivers/pinctrl/realtek/pinctrl-rtd1315e.c | 3 ++- drivers/pinctrl/realtek/pinctrl-rtd1319d.c | 3 ++- 2 files changed, 4 insertions(+), 2 deletions(-) diff --git a/drivers/pinctrl/realtek/pinctrl-rtd1315e.c b/drivers/pinctrl/realtek/pinctrl-rtd1315e.c index 5ab35d73e6f46..10afc736a52bb 100644 --- a/drivers/pinctrl/realtek/pinctrl-rtd1315e.c +++ b/drivers/pinctrl/realtek/pinctrl-rtd1315e.c @@ -227,8 +227,9 @@ static const struct pinctrl_pin_desc rtd1315e_iso_pins[] = { PINCTRL_PIN(RTD1315E_ISO_TESTMODE, "testmode"), }; +/* Tagged as __maybe_unused since there are pins we may use in the future */ #define DECLARE_RTD1315E_PIN(_pin, _name) \ - static const unsigned int rtd1315e_## _name ##_pins[] = { _pin } + static const unsigned int rtd1315e_## _name ##_pins[] __maybe_unused = { _pin } DECLARE_RTD1315E_PIN(RTD1315E_ISO_GPIO_0, gpio_0); DECLARE_RTD1315E_PIN(RTD1315E_ISO_GPIO_1, gpio_1); diff --git a/drivers/pinctrl/realtek/pinctrl-rtd1319d.c b/drivers/pinctrl/realtek/pinctrl-rtd1319d.c index 838a447776ba0..b1a654ac30dcf 100644 --- a/drivers/pinctrl/realtek/pinctrl-rtd1319d.c +++ b/drivers/pinctrl/realtek/pinctrl-rtd1319d.c @@ -233,8 +233,9 @@ static const struct pinctrl_pin_desc rtd1319d_iso_pins[] = { PINCTRL_PIN(RTD1319D_ISO_TESTMODE, "testmode"), }; +/* Tagged as __maybe_unused since there are pins we may use in the future */ #define DECLARE_RTD1319D_PIN(_pin, _name) \ - static const unsigned int rtd1319d_## _name ##_pins[] = { _pin } + static const unsigned int rtd1319d_## _name ##_pins[] __maybe_unused = { _pin } DECLARE_RTD1319D_PIN(RTD1319D_ISO_GPIO_0, gpio_0); DECLARE_RTD1319D_PIN(RTD1319D_ISO_GPIO_1, gpio_1); -- 2.30.2
