Subject[PATCH] hte: tegra194: add GPIOLIB dependency
Date
From: Arnd Bergmann <arnd@arndb.de>

The driver started calling into a few interfaces that are part of GPIOLIB and
don't have stub implementations otherwise:

drivers/hte/hte-tegra194.c: In function 'tegra_hte_line_xlate':
drivers/hte/hte-tegra194.c:424:48: error: implicit declaration of function 'gpio_device_get_base'; did you mean 'gpio_device_get_desc'? [-Werror=implicit-function-declaration]
424 | line_id = desc->attr.line_id - gpio_device_get_base(gs->gdev);
| ^~~~~~~~~~~~~~~~~~~~
| gpio_device_get_desc

Add a Kconfig dependency to only allow building when this is defined.

Fixes: dc850faa28ee0 ("hte: tegra194: don't access struct gpio_chip")
Signed-off-by: Arnd Bergmann <arnd@arndb.de>
