nfc: Switch i2c drivers back to use .probe() After commit b8a1a4cd5a98 ("i2c: Provide a temporary .probe_new() call-back type"), all drivers being converted to .probe_new() and then 03c835f498b5 ("i2c: Switch .probe() to not take an id parameter") convert back to (the new) .probe() to be able to eventually drop .probe_new() from struct i2c_driver.

i2c: Make remove callback return void The value returned by an i2c driver's remove function is mostly ignored. (Only an error message is printed if the value is non-zero that the error is ignored.) So change the prototype of the remove function to return no value. This way driver authors are not tempted to assume that passing an error to the upper layer is a good idea. All drivers are adapted accordingly. There is no intended change of behaviour, all callbacks were prepared to return 0 before.

NFC: nfcmrvl: fix kernel-doc syntax in file headers The opening comment mark '/**' is used for highlighting the beginning of kernel-doc comments. The header for drivers/nfc/nfcmrvl follows this syntax, but the content inside does not comply with kernel-doc. This line was probably not meant for kernel-doc parsing, but is parsed due to the presence of kernel-doc like comment syntax(i.e, '/**'), which causes unexpected warnings from kernel-doc. For e.g., running scripts/kernel-doc -none on drivers/nfc/nfcmrvl/spi.c causes warning: warning: expecting prototype for Marvell NFC(). Prototype was for SPI_WAIT_HANDSHAKE() instead Provide a simple fix by replacing such occurrences with general comment format, i.e. '/*', to prevent kernel-doc from parsing it.
