[Qemu-devel] [PULL 22/55] qcow2: Remove BDS parameter from qcow2_cache_entry_mark_dirty()

[Kevin Wolf <kwolf@redhat.com>]

From: Alberto Garcia <berto@igalia.com>

This function was only using the BlockDriverState parameter to pass it
to qcow2_cache_get_table_idx(). This is no longer necessary so this
parameter can be removed.
