Subject: defxx: Fix DEFPA enable error propagation
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a65da0c3dac6e2d4f8ecf0aee8b0abe10001f2d9;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

defxx: Fix DEFPA enable error propagation

Correctly propagate the error code from `pci_enable_device' if non zero.
Currently a failure of this function is correctly recognized and device
initialization abandoned, however a successful completion code returned.
