Subject[PATCH 06/13] media: atomisp: sh_css_params: cleanup the code
Date
Now that the tests for the new ISP2401 input system were
dropped, simplify the code, making it closer to the Intel
Aero device driver.

To avoid mailbombing on a large number of people, only mailing lists were C/C on the cover.
