From 6cc6c468381e369e6450257645cf65c67f9f4a1b Mon Sep 17 00:00:00 2001 From: Vladimir Shulman Date: Sun, 4 Oct 2015 10:23:21 +0300 Subject: [PATCH] wil6210: pmc logger bug fix When allocating pmc descriptor, the structure is initially created on stack and later copied to the physical ring (device) memory. The descriptor structure must be initialized to zero to avoid garbage configuration, which may result in pmc mechanism malfunctioning.
