[PATCH 1/1] media: pci: meye: set error code on failures

[Pan Bian]

From: Pan Bian <bianpan2016@xxxxxxx>

The value of return variable ret is 0 on some error paths, for example,
when pci_resource_start() returns a NULL pointer. 0 means no error in
this context, which is contrary to the fact. This patch fixes the bug.
