[libcamera-devel] [PATCH 5/6] include: linux: intel-ipu3: Force alignement to 32 bytes

[Jacopo Mondi]

Fix compilation error:
include/linux/intel-ipu3.h:2475:35: error: ‘ipu3_uapi_acc_param::awb_fr’
offset 36756 in ‘ipu3_uapi_acc_param’ isn’t aligned to 32
[-Werror=packed-not-aligned]

by forcing alignment to 32 bytes for struct ipu3_uapi_awb_fr_config_s.

As the header is exported from Linux v5.1 this is a workaround and
should probably be fixed in the kernel headers themselves.
