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.
