Subject: [PATCH] video: fbdev: radeon: Fix memleak in radeonfb_pci_register

[ Upstream commit fe6c6a4af2be8c15bac77f7ea160f947c04840d1 ]

When radeon_kick_out_firmware_fb() fails, info should be
freed just like the subsequent error paths.

Fixes: 069ee21a82344 ("fbdev: Fix loading of module radeonfb on PowerMac")
