While creation of device link, if devm_phy_get() function fails then it 
directly returns PTR_ERR without any cleanup of previous added device 
links.

Added goto statement to handle the cleanup of already added device links.

PCIe and PHY)

No need to repost for this, but when applying, please
s/Added/Add/ in subject and commit log (I mentioned this before for
the v1 posting).

Also add statement in commit log about what the patch does (currently
it only says what the problem is).

And join Fixes: into a single line without a newline in the middle.
