From 4e0e8f87b81ed1dfa9876e0ce4492cc8f64c935a Mon Sep 17 00:00:00 2001

Subject: [PATCH] media: i2c: imx290: Switch set_hmax to use
imx290_write_buffered_reg
imx290_set_hmax was using two independent writes to set up hmax,
when all other multi-register writes were using imx290_write_buffered_reg
which claims the group hold first.
Switch imx290_set_hmax to using imx290_write_buffered_reg too.
