Subject: [PATCH] media: i2c: imx290: Drop imx290_write_buffered_reg()
|
|
|
|
Upstream commit b817888a0c50.
|
|
|
|
The imx290_write_buffered_reg() function wraps a register write with
|
|
register hold, to enable changing multiple registers synchronously. It
|
|
is used for the gain only, which is an 8-bit register, defeating its
|
|
purpose.
|
|
|
|
The feature is useful, but should be implemented differently. Drop the
|
|
function for now, to prepare for a rework of register access.
