Nicholas Kazlauskas 0e9d790276 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.
