Looking pretty good, almost no warnings left. The first one in this list is the only one that already exists in v4.7 (and a long time before that), all other preexisting warnings are fixed in -next.

The kernelci autobuilder finds a couple of other warnings on top of these, because they build more unusual configurations and use some slightly older compilers that produce false positives.

Warnings: 1 drivers/infiniband/core/cma.c:1242:12: warning: 'src_addr_storage.sin_addr.s_addr' may be used uninitialized in this function [-Wmaybe-uninitialized]

I sent a patch on July 4 to the infiniband list but got no reply. It only shows up on powerpc, presumably with an older compiler, so I don't consider this as urgent, the only reason to fix it up would be to get to zero warnings for the common architectures.

Doug, any chance you can still pick up "infiniband: shut up a maybe-uninitialized warning" for 4.8?

  1 drivers/tty/serial/8250/8250_fintek.c:34:0: warning: "IRQ_MODE" redefined

I sent a patch on June 26 to Greg, but he hasn't applied any serial driver patches since June 25, so I assume it's in his queue and will make it into v4.8 without further action on my side.

  2 drivers/media/dvb-frontends/cxd2841er.c:3408:40: warning: 'carrier_offset' may be used uninitialized in this function [-Wmaybe-uninitialized]

It's in patchwork, so I assume Mauro will get to it in time: https://patchwork.linuxtv.org/patch/35398/

The warning was introduced by a patch outside of drivers/media in linux-mm ("dynamic_debug: add jump label support").

  3 drivers/net/wireless/ti/wlcore/spi.c:457:6: warning: unused variable 'ret' [-Wunused-variable]

This came up today, and the author of the patch that broke it already sent a fix "wlcore: spi: fix build warning caused by redundant variable".
