This is a core media file... it shoudn't have so many coding style issues! The last patch ended by being submitted with an error like that, very likely due to some cut and paste issue. Maybe it is time to clean it up. Do it with the auto fix logic: ./scripts/checkpatch.pl -f drivers/media/dvb-core/dvb_frontend.c --strict --fix-inplace Then manually fix the errors introduced by it.

During destruction, a race condition in dvb_media_controller_disable_source() can cause a kernel crash, because the "mdev" pointer has been read successfully while another task executes dvb_usb_media_device_unregister(), which destroys the object.

Arnd Bergmann authored
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. In the process of eliminating the references to 'struct timeval' from the kernel, I also change the way the timestamp is generated internally, basically by open-coding the v4l2_get_timestamp() call.
