| 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.
