If you can't, please send email from a non-Red Hat email address. I don't understand why this is a useful warning to fix. What actual problem is caused by the code below? > return and break > > switch (c->x86_vendor) { > case X86_VENDOR_INTEL: > intel_p5_mcheck_init(c); > return 1; > - break; Sure, it's unnecessary, but it's not masking a bug. It's not unclear. Why do we want to enable this warning? _______________________________________________ Linux-nvdimm mailing list -- linux-nvdimm@lists.01.org To unsubscribe send an email to linux-nvdimm-leave@lists.01.org
