Subject: [PATCH v2 05/15] media: i2c: ds90ub960: Fix logging SP & EQ status
only for UB9702
UB9702 does not have SP and EQ registers, but the driver uses them in
log_status(). Fix this by separating the SP and EQ related log_status()
work into a separate function (for clarity) and calling that function
only for UB960.
Signed-off-by: Tomi Valkeinen <tomi.valkeinen@...asonboard.com>
Fixes: afe267f2d368 ("media: i2c: add DS90UB960 driver")
