ALSA: usb-audio: Fix regression on detection of Roland VS-100
stable inclusion from stable-v5.10.177 commit 3b6992bdf09d7e46e9bfb92a98c4ca1f2779466a category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I88YNP Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=3b6992bdf09d7e46e9bfb92a98c4ca1f2779466a -------------------------------- commit fa4e7a6f upstream. It's been reported that the recent kernel can't probe the PCM devices on Roland VS-100 properly, and it turned out to be a regression by the recent addition of the bit shift range check for the format bits. In the old code, we just did bit-shift and it resulted in zero, which is then corrected to the standard PCM format, while the new code explicitly returns an error in such a case. For addressing the regression, relax the check and fallback to the standard PCM type (with the info output).
