Subject: [PATCH] media: i2c: imx290: Pass format and mode to
|
|
imx290_calc_pixel_rate()
|
|
|
|
Upstream commit 31b54a422b3f
|
|
|
|
Avoid accessing the imx290 current_format and current_mode fields in
|
|
imx290_calc_pixel_rate() to prepare for the removal of those fields.
|
|
Among the two callers of the function, imx290_ctrl_update() has an
|
|
explicit mode pointer already, and we can also give it a format pointer.
|
|
Use those explicitly.
|
|
|
|
While at it, inline the imx290_get_link_freq() function in
|
|
imx290_calc_pixel_rate() as it is only called there.
