button_scan: struct input_event has no member named 'time'

[tux-linux]

Hello,
Compiled FBInk for an initrd once again this morning and I came across an error that I encounter quite frequently these times with it. A quick fix is to pass MINIMAL=1 to the make environment variables, but the normal target fails with the error message I pasted below.
I've tried compiling it with a musl armv7l cross-toolchain (GCC 10.2.1) on a x86_64 Debian 10 VM.
Probably some musl-specific stuff I'd guess, although IIRC I've encountered this with other (non-musl) toolchains before too...

That's due to this change in Linux 4.16. You'll need to compile with an older toolchain build with the correct headers for Kobo's kernel, or @NiLuJe will need to add -D_TIME_BITS=32 to the compile options.
