* nfc: pn533: Fix double free when pn533_fill_fragment_skbs() failsChengfeng Ye2021-11-071-3/+3
| | | | | | | | | | | | | | skb is already freed by dev_kfree_skb in pn533_fill_fragment_skbs, but follow error handler branch when pn533_fill_fragment_skbs() fails, skb is freed again, results in double free issue. Fix this by not free skb in error path of pn533_fill_fragment_skbs.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During probing, the driver tries to get a list (mask) of supported command types in port100_get_command_type_mask() function. The value is u64 and 0 is treated as invalid mask (no commands supported). The function however returns also -ERRNO as u64 which will be interpret as valid command mask. Return 0 on every error case of port100_get_command_type_mask(), so the probing will stop.

So don't skip disabling the regulator in st95hf_remove() if resetting the controller via spi fails. Also don't return an error code which just results in two error messages.
