2019-03-22staging: mt7621-mmc: Check for nonzero number of scatterlist entriesGeorge Hilliard1-2/+7
The buffer descriptor setup loop is correct only if it is setting up at least one bd struct. Besides, there is an error if dma_map_sg() returns 0, which is possible and must be handled. Additionally, remove the BUG_ON() checking sglen, which is unnecessary because we configure DMA with that constraint during init.

2019-03-21staging: rtl8712: uninitialized memory in read_bbreg_hdl()Dan Carpenter2-10/+2
Colin King reported a bug in read_bbreg_hdl(): memcpy(pcmd->rsp, (u8 *)&val, pcmd->rspsz); The problem is that "val" is uninitialized. This code is obviously not useful, but so far as I can tell "pcmd->cmdcode" is never GEN_CMD_CODE(_Read_BBREG) so it's not harmful either. For now the easiest fix is to just call r8712_free_cmd_obj() and return.
