Subject: pci_rom.c: Fix may be used uninitialized warning
X-Git-Tag: v2016.03-rc1~292

pci_rom.c: Fix may be used uninitialized warning

With gcc-5.x we get:
drivers/pci/pci_rom.c: In function 'dm_pci_run_vga_bios':
drivers/pci/pci_rom.c:352:3: warning: 'ram' may be used uninitialized in
this function [-Wmaybe-uninitialized]

While unconvinced that this can happen in practice (if we malloc we set
alloced to true, it will be false otherwise), silence the compiler.
