Subject[PATCH] Staging: comedi: fix memory leak in comedi_bond.c
Date
We allocate bdev and then krealloc the devs pointer in order to add bdev
at the end of the devpriv->devs array list. But if for some reason this
krealloc fails, we need to free bdev before returning an error otherwise
this memory is leaked.
