This patch fixes the same by making ctm max test independent of gamma/degamma. v2: Disable degamma/gamma programming for ctm max test as it leads to crc mimsmatch. Limiting it to this test case alone as other tests need it to be enabled, hence not touching those scenarios. v3: Fixed a fumble with compilation. v4: Disabling degamma and gamma for ctm max tests, after the logic in kernel has been updated by Ville's series. v5: Disabled gamma/degamma for all ctm tests as suggested by Ville. v6: Restricting disabling of linear gamma luts for ctm max test. Updated the commit message and comment as suggested by Daniel.
