Subject: [PATCH] media: atomisp: make atomisp_css_continuous_set_num_raw_frames() void

From: Kaixu Xia <[email protected]>

The return value of atomisp_css_continuous_set_num_raw_frames() function
is always 0, so there's no reason for a return value. In addition, the
__enable_continuous_mode() checked the return value for possible error
which is unnecessary. Convert atomisp_css_continuous_set_num_raw_frames()
to a void function.
