nfc: pn533: Fix double free when pn533_fill_fragment_skbs() fails

2021-11-18T18:17:10+00:00

[ Upstream commit 9fec40f850658e00a14a7dd9e06f7fbc7e59cc4a ] 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.

nfc: port100: fix using -ERRNO as command type mask

2021-10-26T12:42:00+00:00

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.

nfc: st95hf: Make spi remove() callback return zero

2021-10-20T13:41:20+00:00

If something goes wrong in the remove callback, returning an error code just results in an error message. The device still disappears. 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.

nfc: st-nci: Add SPI ID matching DT compatible

2021-09-23T11:53:06+00:00

Currently autoloading for SPI devices does not use the DT ID table, it uses SPI modalises. Supporting OF modalises is going to be difficult if not impractical, an attempt was made but has been reverted, so ensure that module autoloading works for this driver by adding the part name used in the compatible to the list of SPI IDs.
