Christian Engelmayer b771852270 [media] as102: fix potential double free in as102_fw_upload()
In case the request to locate the firmware file part 2 fails, the error
path releases the already freed firmware memory location again. Thus
reset the firmware pointer to NULL after releasing firmware file part 1.

Julia Lawall bfe40b79e9 [media] as102: fix error return code
Return a negative error code on failure.

A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)

// <smpl>
@@
identifier ret; expression e1,e2;
@@
(
if (\(ret < 0\|ret != 0\))
 { ... return ret; }
|
ret = 0
)
... when != ret = e1
    when != &ret
*if(...)
{
  ... when != ret = e2
      when forall
 return ret;
}
// </smpl>

This happens because of the command endiannes that are sent/received to
the firmware. So, add the correct endiannes tags to the command fields.

Dan Carpenter 271430efb2 [media] as102: remove some unneeded checks
We know "ret" is zero so we don't need to test for it.  It upsets the
static checkers when we test stuff but we know the answer.

drivers/media/usb/as102/as102_usb_drv.c:164 as102_send_ep1() warn: we tested 'ret' before and it was 'false'
drivers/media/usb/as102/as102_usb_drv.c:189 as102_read_ep2() warn: we tested 'ret' before and it was 'false'

Also, we don't need to initialize "ret".
