[PATCH 3/8] [media] s5p-jpeg: Add m2m_ops field to the s5p_jpeg_variant structure

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Simplify the code by adding m2m_ops field to the
s5p_jpeg_variant structure which allows to avoid
"if" statement in the s5p_jpeg_probe function.
