[PATCH] gpio: tegra: fix debugfs compile error

From: Arnd Bergmann
Date: Mon Jul 08 2019 - 08:38:54 EST


Without this header, some configurations now run into a build failure:

drivers/gpio/gpio-tegra.c:665:2: error: implicit declaration of function 'debugfs_create_file'
[-Werror,-Wimplicit-function-declaration]
debugfs_create_file("tegra_gpio", 0444, NULL, tgi,
^
drivers/gpio/gpio-tegra.c:665:2: error: this function declaration is not a prototype [-Werror,-Wstrict-prototypes]
drivers/gpio/gpio-tegra.c:666:9: error: use of undeclared identifier 'tegra_dbg_gpio_fops'

Remove the #ifdef here and let the compiler drop the unused
functions itself when debugfs_create_file() is an empty inline
function.

Fixes: a4de43049a1d ("gpio: tegra: Clean-up debugfs initialisation")
