Subject: [PATCH] linux-user: Remove redundant null check and replace free by
|
|
g_free
|
|
|
|
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.
