#1243990 — [PATCH 0/2] atm: iphase: Fix misleading indention and return -ENOMEM on error

OK here it goes ...

There are three non-indention specific smatch warnings in atm/iphase.c

drivers/atm/iphase.c:115 ia_enque_rtn_q() warn: returning -1 instead of -ENOMEM is sloppy
drivers/atm/iphase.c:148 ia_hack_tcq() warn: if();
drivers/atm/iphase.c:1178 rx_pkt() warn: curly braces intended?

this series fixes two of them. The if(); warning would require
restructuring the code to a larger extend. Beyond this there remains a
whooping number of > 2k checkpatch.pl warnings and errors each. Those
can be grouped into 

- Direct usage of printk()
- Style issues concerning operators
- Style issues concerning {}
- Indention with spaces, mixed tabs and spaces etc
- Trailing white-spaces

Generally I would not mind cleaning all this up for those who have to
make functional changes to the driver. However, I would like to know
from the maintainers if such an afford would be welcome or not.

Regards,
Tillmann Heidsieck

#1243992 — [PATCH 1/2] atm: iphase: return -ENOMEM instead of -1 in case of failed kmalloc()

Smatch complains about returning hard coded error codes, silence this
warning.

It doesn't bother me if you do this.  I can review it.
