Greg Kroah-Hartman a9acc03ab8 Revert "uapi/linux/const.h: prefer ISO-friendly __typeof__"
This reverts commit 8fabf09fb1 which is
commit 31088f6f7906253ef4577f6a9b84e2d42447dba0 upstream.

It breaks the CRC generation of loads of symbols, and is not needed at
all for any real Android issue at this point in time, so revert it to
preserve the ABI.

Bug: 161946584
