Joe Hattori 23ea763880 platform/x86: mlx-platform: call pci_dev_put() to balance the refcount ...

[ Upstream commit 185e1b1d91 ]

mlxplat_pci_fpga_device_init() calls pci_get_device() but does not
release the refcount on error path. Call pci_dev_put() on the error path
and in mlxplat_pci_fpga_device_exit() to fix this.

This bug was found by an experimental static analysis tool that I am
developing.
