spi: ST ST95HF NFC: declare missing of table

2019-05-16T17:40:25Z

[ Upstream commit d04830531d0c4a99c897a44038e5da3d23331d2f ] Add missing table for SPI driver relying on SPI device match since compatible is in a DT binding or in a DTS.

networking: add and use skb_put_u8()

2017-06-16T15:48:40Z

Joe and Bjørn suggested that it'd be nicer to not have the cast in the fairly common case of doing *(u8 *)skb_put(skb, 1) = c; Add skb_put_u8() for this case, and use it across the code, using the following spatch: @@ expression SKB, C, S; typedef u8; identifier fn = {skb_put}; fresh identifier fn2 = fn ## "_u8"; @@ - *(u8 *)fn(SKB, S) = C; + fn2(SKB, C); Note that due to the "S", the spatch isn't perfect, it should have checked that S is 1, but there's also places that use a sizeof expression like sizeof(var) or sizeof(u8) etc. Turns out that nobody ever did something like *(u8 *)skb_put(skb, 2) = c; which would be wrong anyway since the second byte wouldn't be initialized.

networking: make skb_put & friends return void pointers

2017-06-16T15:48:39Z

It seems like a historic accident that these return unsigned char *, and in many places that means casts are required, more often than not. Make these functions (skb_put, __skb_put and pskb_put) return void * and remove all the casts across the tree, adding a (u8 *) cast only where the unsigned char pointer was used directly, all done with the following spatch: @@ expression SKB, LEN; typedef u8; identifier fn = { skb_put, __skb_put }; @@ - *(fn(SKB, LEN)) + *(u8 *)fn(SKB, LEN) @@ expression E, SKB, LEN; identifier fn = { skb_put, __skb_put }; type T; @@ - E = ((T *)(fn(SKB, LEN))) + E = fn(SKB, LEN) which actually doesn't cover pskb_put since there are only three users overall. A handful of stragglers were converted manually, notably a macro in drivers/isdn/i4l/isdn_bsdcomp.c and, oddly enough, one of the many instances in net/bluetooth/hci_sock.c. In the former file, I also had to fix one whitespace problem spatch introduced. Signed-off-by: Johannes Berg Signed-off-by: David S. Miller
