[Qemu-devel] [PATCH] ide: fix invalid TRIM range abortion for macio

[Anton Nefedov <anton.nefedov@virtuozzo.com>]

commit 947858b0 "ide: abort TRIM operation for invalid range"
is incorrect for macio; just ide_dma_error() without doing a callback
is not enough for that errorpath.

Instead, pass -EINVAL to the callback and handle it there
(see related motivation for read/write in 58ac32113).

It will however catch possible EINVAL from the block layer too.
