[PATCH] net: tulip: Adjust indentation in {dmfe,uli526x}_init_module

[Nathan Chancellor]

Clang warns:

../drivers/net/ethernet/dec/tulip/uli526x.c:1812:3: warning: misleading
indentation; statement is not part of the previous 'if'
[-Wmisleading-indentation]
switch (mode) {
^
../drivers/net/ethernet/dec/tulip/uli526x.c:1809:2: note: previous
statement is here
if (cr6set)
^
1 warning generated.

../drivers/net/ethernet/dec/tulip/dmfe.c:2217:3: warning: misleading
indentation; statement is not part of the previous 'if'
[-Wmisleading-indentation]
switch(mode) {
^
../drivers/net/ethernet/dec/tulip/dmfe.c:2214:2: note: previous
statement is here
if (cr6set)
^
1 warning generated.

This warning occurs because there is a space before the tab on these
lines. Remove them so that the indentation is consistent with the Linux
kernel coding style and clang no longer warns.

While we are here, adjust the default block in dmfe_init_module to have
a proper break between the label and assignment and add a space between
the switch and opening parentheses to avoid a checkpatch warning.

/^ \t
in vim turns up a few more cases that I think should be fixed (in both files)

Applied, but it's really crummy that the tool gets tripped up by the
fact that a space preceeds the TAB. It's what the code visually looks
like, not what exact kinds of SPACE characters were used to get there.

[Nathan Chancellor]

I agree. There is a follow up patch from the author of the warning that
claims to alieviate some of these but that is still in discussion and as
far as I understand it, it won't fix all of them so I'm just dealing
with all of them on the Linux side.

Thanks for picking them up!
