62519b10a4 powerpc/powernv: Free name on error in opal_event_init()
[ Upstream commit cf8989d20d64ad702a6210c11a0347ebf3852aa7 ]

In opal_event_init() if request_irq() fails name is not freed, leading
to a memory leak. The code only runs at boot time, there's no way for a
user to trigger it, so there's no security impact.

Fix the leak by freeing name in the error path.

40719c8bbd powerpc/powernv: Add a null pointer check in opal_event_init()
[ Upstream commit 8649829a1dd25199bbf557b2621cedb4bf9b3050 ]

kasprintf() returns a pointer to dynamically allocated memory
which can be NULL upon failure.
