[PATCH 2/2] media: i2c: ds90ub960: Fix PLL config for 1200 MHz CSI rate

From: Tomi Valkeinen
Date: Thu Aug 03 2023 - 04:42:15 EST


smatch reports:

drivers/media/i2c/ds90ub960.c:1788 ub960_init_tx_ports() error: uninitialized symbol 'pll_div'.

This is caused by 'pll_div' not being set for 1200 MHz CSI rate. Set the
'pll_div' correctly.

Fixes: afe267f2d368 ("media: i2c: add DS90UB960 driver")
