Subject: [PATCH] iio: light: rpr0521: add missing Kconfig dependencies
Git-commit: 6ac12303572ef9ace5603c2c07f5f1b00a33f580
Patch-mainline: v6.1-rc7
References: git-fixes
Fix an implicit declaration of function error for rpr0521 under some configs
When CONFIG_RPR0521 is enabled without CONFIG_IIO_TRIGGERED_BUFFER,
the build results in "implicit declaration of function" errors, e.g.,
drivers/iio/light/rpr0521.c:434:3: error: implicit declaration of function
'iio_trigger_poll_chained' [-Werror=implicit-function-declaration]
434 | iio_trigger_poll_chained(data->drdy_trigger0);
| ^~~~~~~~~~~~~~~~~~~~~~~~
This fix adds select dependencies to RPR0521's configuration declaration.
Fixes: e12ffd241c00 ("iio: light: rpr0521 triggered buffer")

Say Y here if you want to build support for ROHM's RPR0521
ambient light and proximity sensor device.
