[Qemu-devel] [PATCH] linux-user: Remove redundant null check and replace free by g_free

[Stefan Weil]

Report from smatch:

linux-user/syscall.c:3632 do_ioctl_dm(220) info:
 redundant null check on big_buf calling free()

'big_buf' was allocated by g_malloc0, therefore free was also
replaced by g_free.
