Possibly this is one configuration that disables -Wmaybe-uninitialized in later kernels, though I can't see why. > tb0226_defconfig (mips) — FAIL, 96 errors, 4 warnings, 0 section mismatches > drivers/scsi/scsi_tgt_if.c:289:36: warning: passing argument 1 of > 'virt_to_phys' makes pointer from integer without a cast [-Wint-conversion] The driver was removed in 3.17. > workpad_defconfig (mips) — FAIL, 96 errors, 4 warnings, 0 section mismatches > Warnings: > drivers/net/ethernet/amd/nmclan_cs.c:624:3: warning: > 'pcmcia_request_exclusive_irq' is deprecated [-Wdeprecated-declarations] The warning was addressed by 5f5316fcd08e ("am2150: Update nmclan_cs.c to use update PCMCIA API") though that patch seems wrong. I think I sent a better one at the time.
