C libraries with 64-bit time_t use an incompatible format for struct omap3isp_stat_data. This changes the kernel code to support either version, by moving over the normal handling to the 64-bit variant, and adding compatiblity code to handle the old binary format with the existing ioctl command code. Fortunately, the command code includes the size of the structure, so the difference gets handled automatically. Signed-off-by: Arnd Bergmann <arnd@arndb.de> --- This patch was originally part of a longer series, along with other patches that we still have to rewrite for the generic ioctl interface, but the OMAP specific ioctl commands are completely independent of that, so I think we can just merge this version for 4.8. in v4, I'm fixing a build regression that was introduced v3, which separated this patch from the v4l_timeval type that I had in the earlier versions. --- drivers/media/platform/omap3isp/isph3a_aewb.c | 2 ++ drivers/media/platform/omap3isp/isph3a_af.c | 2 ++ drivers/media/platform/omap3isp/isphist.c | 2 ++ drivers/media/platform/omap3isp/ispstat.c | 18 +++++++++++++++++- drivers/media/platform/omap3isp/ispstat.h | 2 ++ include/uapi/linux/omap3isp.h | 22 ++++++++++++++++++++++ 6 files changed, 47 insertions(+), 1 deletion(-)
