drm/amd/display: invalid parameter check in dmub_hpd_callback
The function performs a check on the "adev" input parameter, however, it
is used before the check.
Initialize the "dev" variable after the sanity check to avoid a possible
NULL pointer dereference.
Fixes: e27c41d5b0681 ("drm/amd/display: Support for DMUB HPD interrupt handling")
Addresses-Coverity-ID: 1493909 ("Null pointer dereference")
