[PATCH V2 11/19] irqchip: crossbar: fix memory leak incase of invalid entry

From: Sricharan R
Date: Thu Jun 12 2014 - 07:56:52 EST


From: Nishanth Menon <nm@xxxxxx>

When the provided unused skip list entry is greater than max irqs
possible, we go to err3, but we fail to free register_offsets,
should have returned to err4 instead which ensures that allocated
register_offsets are freed as well.
