From: Jérôme Pouiller Date: Wed, 15 Jan 2020 13:55:03 +0000 (+0000) Subject: staging: wfx: do not update uapsd if not necessary X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=9b90910f5bf4d6c76bbd55fcda5baa0ff015060b;p=linux.git staging: wfx: do not update uapsd if not necessary wfx_conf_tx() is called for each queue. On every call, the function updates UAPSD mask and PM mode for all queues. It is a pity since the UAPSD configuration very rarely changes and it makes exchanges between the host and the chip more difficult to track. This patch avoid to update UAPSD and Power Mode in most usual cases.
