This caught my eye and brought up an issue I've been wondering about for some time: On Fri, 28 Aug 2020, Maxime Ripard wrote: > On Sat, Jul 25, 2020 at 08:25:50PM -0500, Samuel Holland wrote: > > ... some DAPM widgets still have incorrect or confusing names; those > > and other issues will be fixed in later patch sets. As a general and firm rule in the Linux kernel when it comes to upgrades and fixes is "We do not break userspace". Which means that for instance an application must not stop working after a kernel upgrade due to some API changing. So does this mean that the name of an ALSA control, once it's in the mainline kernel, can never be changed, for whatever reason? Or devicetree properties, does the same apply there? Say a property as a confusing name, is it possible to change it at all? Or are these things open to debate, depending on the severity and consequences etc? /Ricard -- Ricard Wolf Wanderlof ricardw(at)axis.com Axis Communications AB, Lund, Sweden www.axis.com Phone +46 46 272 2016 Fax +46 46 13 61 30
