Modified files: sys/dev/pci : if_iwxreg.h Log message: Fix an alignment issue in iwx(4) Rx descriptors. Split a 64-bit field, aligned at a 4-byte boundary, into two 32 bit fields. Our driver does not use this field. Its definition does not matter to us, as long as its size remains correct. Fixes clang-15 warnings, which turn into compilation errors with -Werror. Reported by, and ok tb@ Relevant clang 15 errors are: In file included from /sys/dev/pci/if_iwx.c:151: /sys/dev/pci/if_iwxreg.h:3659:2: error: field within 'struct iwx_rx_mpdu_desc_v1' is less aligned than 'union iwx_rx_mpdu_desc_v1::(anonymous at /sys/dev/pci/if_iwxreg.h:3659:2)' and is usually due to 'struct iwx_rx_mpdu_desc_v1' being packed, which can lead to unaligned accesses [-Werror,-Wunaligned-access] union { ^ /sys/dev/pci/if_iwxreg.h:3626:2: error: field within 'struct iwx_rx_mpdu_desc_v3' is less aligned than 'union iwx_rx_mpdu_desc_v3::(anonymous at /sys/dev/pci/if_iwxreg.h:3626:2)' and is usually due to 'struct iwx_rx_mpdu_desc_v3' being packed, which can lead to unaligned accesses [-Werror,-Wunaligned-access] union { ^ 2 errors generated.
