[ Upstream commit 6ac12303572ef9ace5603c2c07f5f1b00a33f580 ]
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")

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
