Subject: [PATCH v2] iio: fix kernel-doc warnings in industrialio-backend.c

From: Kriish Sharma <kriish.sharma2006@...il.com>

Fix multiple kernel-doc warnings in drivers/iio/industrialio-backend.c,
including a missing description for the @chan parameter in
iio_backend_oversampling_ratio_set() and a missing return value
description in iio_backend_get_priv().

This addresses the warnings reported by kernel-doc and the kernel test
robot.

Reported-by: kernel test robot <lkp@...el.com>
Closes: https://lore.kernel.org/oe-kbuild-all/202506292344.HLJbrrgR-lkp@intel.com
Suggested-by: Andy Shevchenko <andy@...nel.org>
Signed-off-by: Kriish Sharma <kriish.sharma2006@...il.com>
