6.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Narasimharao Vadlamudi <ahmisaranrao@gmail.com>

commit 8cd5735b88d76dda80b089031747b6f18ee0bca2 upstream.

imx415_set_testpattern() accumulates failures from cci_write(), but drops
the value and always returns success. Return the accumulated error so V4L2
reports failures to userspace.

Fixes: d5df1c7f3f83 ("media: i2c: imx415: Convert to new CCI register access helpers")
