2017-11-06nfc: s3fwrn5: make array match static constColin Ian King
Don't populate the read-only array match on the stack, instead make it static const. Makes the object code smaller by over 310 bytes: Before: text data bss dec hex filename 8304 1084 128 9516 252c drivers/nfc/s3fwrn5/firmware.o After: text data bss dec hex filename 7894 1180 128 9202 23f2 drivers/nfc/s3fwrn5/firmware.o Signed-off-by: Colin Ian King <colin.king@canonical.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2017-11-06nfc: s3fwrn5: constify i2c_device_idArvind Yadav
i2c_device_id are not supposed to change at runtime. All functions working with i2c_device_id provided by <linux/i2c.h> work with const i2c_device_id. So mark the non-const structs as const. Signed-off-by: Arvind Yadav <arvind.yadav.cs@gmail.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2017-06-16networking: introduce and use skb_put_data()Johannes Berg
A common pattern with skb_put() is to just want to memcpy() some data into the new space, introduce skb_put_data() for this. An spatch similar to the one for skb_put_zero() converts many of the places using it: @@ identifier p, p2; expression len, skb, data; type t, t2; @@ ( -p = skb_put(skb, len); +p = skb_put_data(skb, data, len); | -p = (t)skb_put(skb, len); +p = skb_put_data(skb, data, len); ) ( p2 = (t2)p; -memcpy(p2, data, len); | -memcpy(p, data, len); ) @@ type t, t2; identifier p, p2; expression skb, data; @@ t *p; ... ( -p = skb_put(skb, sizeof(t)); +p = skb_put_data(skb, data, sizeof(t)); | -p = (t *)skb_put(skb, sizeof(t)); +p = skb_put_data(skb, data, sizeof(t)); ) ( p2 = (t2)p; -memcpy(p2, data, sizeof(*p)); | -memcpy(p, data, sizeof(*p)); ) @@ expression skb, len, data; @@ -memcpy(skb_put(skb, len), data, len); +skb_put_data(skb, data, len); (again, manually post-processed to retain some comments) Reviewed-by: Stephen Hemminger <stephen@networkplumber.org> Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: David S.
