commit 9e38acacb9d809b97a0bdc5c76e725355a47158a upstream.
The mask to select the test-pattern in register ADV748X_SDP_FRP is incorrect, it's the lower 3 bits which controls the pattern. The GENMASK() macro is used incorrectly and the generated mask is 0x0e instead of 0x07.
The result is that not all test patterns are selectable, and that in some cases the wrong test pattern is activated. Fix this by correcting the GENMASK().
