[PATCH 4.3 050/200] tpm_tis: free irq after probing

From: Greg Kroah-Hartman
Date: Sun Feb 14 2016 - 17:41:58 EST


4.3-stable review patch. If anyone has any objections, please let me know.

------------------

From: Martin Wilck <Martin.Wilck@xxxxxxxxxxxxxx>

commit 2aef9da60bfdeb68dbcd4f114c098cbaa841b4ee upstream.

Release IRQs used for probing only. Otherwise the TPM will end up
with all IRQs 3-15 assigned.

Fixes: afb5abc262e9 ("tpm: two-phase chip management functions")
