linux.git/drivers/net/wireless/ath, branch v6.15 Linux kernel source tree gcc-15: add '__nonstring' markers to byte arrays 2025-04-20T18:57:54+00:00 Linus Torvalds torvalds@linux-foundation.org 2025-04-20T18:18:55+00:00 05e8d261a34e5c637e37be55c26e42cf5c75ee5c All of these cases are perfectly valid and good traditional C, but hit by the "you're not NUL-terminating your byte array" warning. And none of the cases want any terminating NUL character. Mark them __nonstring to shut up gcc-15 (and in the case of the ak8974 magnetometer driver, I just removed the explicit array size and let gcc expand the 3-byte and 6-byte arrays by one extra byte, because it was the simpler change).
