Subject: [PATCH 0/2] tpm: add optional max xfer size check
Date: Thu, 14 Jul 2016 18:39:03 -0700	[thread overview]
Message-ID: <1468546745-14646-1-git-send-email-apronin@chromium.org> (raw)

This patchset introduces an optional maximum transfer size that can
be specified by a tpm driver. Setting the max_xfer_size helps to catch
the cases when burstcnt is incorrectly reported by the device (e.g. >64
for spi - happened in practice) and gracefully handle such situations.
