linux-next: build warning after merge of the final tree (net-next tree related)

linux-next: build warning after merge of the final tree (net-next tree related)

[Stephen Rothwell]

[-- Attachment #1: Type: text/plain, Size: 466 bytes --]

Hi all,

After merging the final tree, today's linux-next build (sparc32 defconfig)
produced this warning:

drivers/net/ethernet/sun/sunbmac.c: In function 'bigmac_set_multicast':
drivers/net/ethernet/sun/sunbmac.c:998:6: warning: unused variable 'i' [-Wunused-variable]

Introduced by commit bfd428daaf61 ("net: ethernet: sun: initialize
variables directly") from the net-next tree.

Thank you for notifying.

After a second look at the code, I see the apple and korina patch
counterparts also leave an extra i variable now; the dm9000 patch should
be unaffected as it still uses i for other things.

@David, what would you like me to do? I can send another set of patches
fixing this, resend the full original series but fixed, or resend just
the affected patches.

Your patch series is in my tree and will not be reverted, we never do
that.  Therefore you must send me patches which fix up these problems.

[PATCH 1/3] net: ethernet: apple: drop unused variable

[Emilio López]

Commit 3b0aaef ("net: ethernet: apple: initialize variables directly")
dropped the only loop that was using i but did not remove the actual
variable, therefore causing a warning when building. This patch drops
the now redundant line.

I see that you applied the series in net instead of net-next; the
previous patches were in net-next only. This will cause build breakage
in net because the loop is still there.

My bad, I'll fix this up.
