Linux 5.4 rc5

So usually by this time, I wish things were calming down. We've had afew fairly small rc's so far in the 5.4 series, and sadly rc5 isn'tshrinking from that smaller baseline.So unlike the previous rc's that were on the smaller side compared torecent releases, 5.4-rc5 is a bit _bigger_ than the rc5's of the lastfew releases. It's not huge, by any means, and partly exactly becauseprevious rc's were small, I'm going to treat it as just some pent-upwork going in, and I'm not worried.So things still seem pretty normal, and none of the patches look allthat scary to me.I'm still on the road, with OSS EU starting tomorrow, but apart from afew long flights I should be fairly normally responsive and my travelsshouldn't be impacting the upcoming week. Particularly since I hopethat we'll at least start seeing a proper calming down period for rc6.Anyway, shortlog is appended below for people who want to scan thedetails. It's all very normal, with about half of the patch beingdrivers (sound, pinctrl, regulator, gpu, cpufreq, usb..), with therest being arch updates, filesystem updates, misc core stuff anddocumentation.So we have a bit more fixes than normal during this stage, but nothinglooks very strange, and the diffstat looks _mostly_ flat (with thecpufrequency power-QoS and io_uring changes looking a bit bigger)which is my sign for "small changes all over".Go test,          Linus
