[LTP] [PATCH v2 0/3] tst_device.c: Handle Android path for backing device

[Petr Vorel]

> e1b1ae66b240 ("tst_find_backing_dev: Get dev name from
> /sys/dev/block/*/uevent") added a hardcoded path to check for the
> backing device in /dev.  On Android, it needs to check /dev/block.

Cc the original autor.

I guess both problems were unnoticed because they are kind of corner cases
(minimal Linux and Android). But sure we're happily accept patches to fix them.

Kind regards,
Petr
