[PATCH 5.4 139/183] media: ttpci: fix two memleaks in budget_av_attach

[Sasha Levin]

From: Zhipeng Lu <alexious@xxxxxxxxxx>

[ Upstream commit d0b07f712bf61e1a3cf23c87c663791c42e50837 ]

When saa7146_register_device and saa7146_vv_init fails, budget_av_attach
should free the resources it allocates, like the error-handling of
ttpci_budget_init does. Besides, there are two fixme comment refers to
such deallocations.

Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2")
