Subject: [PATCH net 1/1] net: ipa: don't be a hog in gsi_channel_poll()
Date: Fri, 15 May 2020 14:52:03 -0500 [thread overview]
Message-ID: <20200515195203.24947-1-elder@linaro.org> (raw)
The iteration count value used in gsi_channel_poll() is intended to
limit poll iterations to the budget supplied as an argument. But
it's never updated.
Fix this bug by incrementing the count each time through the loop.
