Subject: [PATCH v0 6/6] media: chips-media: wave5: Fix timeout while testing 10bit hevc fluster

521C Wave5 variant does not support 10 bit. When 10 bit support for 515
variant was added, the code which returns an error was removed. While
testing 10bit hevc fluster on the 521C hw, timeout happened.

Fixes: 143e7ab4d9a0 ("media: chips-media: wave5: support decoding HEVC Main10 profile")
