Fix uninitialized variable in ath6kl ath6kl_sdio_enable_scatter

gcc 4.8 warns

In function 'ath6kl_sdio_enable_scatter':

  if (virt_scat || ret) {
                ^

The variable can indeed be uninitialized when the previous if branch is skipped. I just set it to zero for now. I'm not fully sure the fix is correct, maybe the || should be an && ?

something. I think your patch is correct way to fix this.

Thanks, applied to ath6kl.git. I just added "ath6kl:" prefix to the title.
