fw_cfg: fix FW_CFG_BOOT_DEVICE update on ppc and sparc
On ppc, sparc, and sparc64, the value of the FW_CFG_BOOT_DEVICE 16bit fw_cfg entry is repeatedly modified from a series of callbacks, which currently results in the previous value's dynamically allocated memory being leaked. This patch switches updating to the new fw_cfg_modify_i16() call, which does not cause memory leaks. Signed-off-by: Gabriel Somlo <somlo@cmu.edu> Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
