| Subject: media: ov7670: restore default settings after power-up |
| |
| [ Upstream commit 32ab688b280301f7cee9e547564cb74e33e06322 ] |
| |
| Since commit 3d6a8fe25605 ("media: ov7670: hook s_power onto v4l2 core"), |
| the device is actually powered off while the video stream is stopped. |
| |
| The frame format and framerate are restored right after power-up, but |
| restoring the default register settings is forgotten. |
| |
| Fixes: 3d6a8fe25605 ("media: ov7670: hook s_power onto v4l2 core") |
