Nicholas Kazlauskas a64255a476 drm/amd/display: Guard against NULL pointer deref when get_i2c_info fails ... [ Upstream commit 44a09e3d95bd2b7b0c224100f78f335859c4e193 ] [Why] If the BIOS table is invalid or corrupt then get_i2c_info can fail and we dereference a NULL pointer. [How] Check that ddc_pin is not NULL before using it and log an error if it is because this is unexpected.
