Subject: staging: wfx: device already handle sleep mode during scan
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=7ceb4753ef58185b5a90ccbd3a55373b01a38219;p=linux.git

staging: wfx: device already handle sleep mode during scan

The device is not allowed to enter in sleep mode during scan. However,
this is already handled by the device. So driver does not have to care
about it.
