Subject: [PATCH 1/9] irqchip/gic-v3-its: Fix command buffer allocation
Date: Wed, 8 Feb 2017 09:31:00 -0600	[thread overview]
Message-ID: <278df776-4d6d-3b89-7a94-effaafcebeb0@codeaurora.org> (raw)
In-Reply-To: <20170208144328.GS5020@rric.localdomain>

Hi Marc,

In teardown path, code is still calling 'kfree(its->cmd_base)' to free 
memory, this should be changed to 'free_pages(get_order(ITS_CMD_QUEUE_SZ).
