In such scenario,\nintel_hdcp_gsc_check_status() results in a kernel pagefault error due to\n&gt->uc.gsc being evaluated as an invalid memory address.\n\nFix that by introducing a NULL check on media_gt and bailing out early\nif so.\n\nWhile at it, also drop the NULL check for gsc, since it can't be NULL if\nmedia_gt is not NULL.\n\nv2:\n  - Get address for gsc only after checking that gt is not NULL.\n    (Shuicheng)\n  - Drop the NULL check for gsc.
