[PATCH] acpi: EINJ: mark remove callback as non-__exit

[PATCH] acpi: EINJ: mark remove callback as non-__exit

[Arnd Bergmann]

From: Arnd Bergmann <arnd@arndb.de>

The remove callback of a device is called whenever it is unbound,
which may happen during runtime e.g. through sysfs, so this is not
allowed to be dropped from the binary:

WARNING: modpost: vmlinux: section mismatch in reference: einj_driver+0x8 (section: .data) -> einj_remove (section: .exit.text)
ERROR: modpost: Section mismatches detected.

Remove that annotation.

Fixes: 12fb28ea6b1c ("EINJ: Add CXL error type support")

Looks good, not sure why the build robots missed this while this was
sitting in -next. Yes, this was a side effect of reusing the former
einj_exit() as the device remove callback.

Rafael, can you pick this up?
