linux_kselftest_active-fixes-6.6-rc7

Browse Source 
This Kselftest update for Linux 6.6-rc7 consists of one single fix
 to assert check in user_events abi_test to properly check bit value
 on Big Endian architectures. The current code treats the bit values
 as Little Endian and the check fails on Big Endian.
