[Krzysztof Kozlowski]

Since structure comments are not kerneldoc, remove the double ** to fix
W=1 warnings:

[PATCH 02/12] nfc: fdp: drop ACPI_PTR from device ID table

[Krzysztof Kozlowski]

The driver can match only via the ACPI ID table so the table should be
always used and the ACPI_PTR does not have any sense.  This fixes fixes

[PATCH 04/12] nfc: pn533: drop of_match_ptr from device ID table

[Krzysztof Kozlowski]

The driver can match only via the DT table so the table should be always
used and the of_match_ptr does not have any sense (this also allows ACPI
matching via PRP0001, even though it might be not relevant here).  This
fixes compile warning (!CONFIG_OF):
