Subject: linux-next: pcmcia tree build warning

Hi Dominik,

Today's linux-next build (x86_64 allmodconfig) produced this warning:

drivers/char/pcmcia/cm4000_cs.c: In function 'cmm_ioctl':
/scratch/sfr/next/drivers/char/pcmcia/cm4000_cs.c:1630: warning: the frame size of 2176 bytes is larger than 2048 bytes

Introduced by commit 7194198b163c83725f52ce8e34b24cca053deea7 ("pcmcia:
use dynamic debug infrastructure, deprecate CS_CHECK (char)") which
unconditionalised "char *ioctl_names[CM_IOC_MAXNR + 1]" on the stack.
CM_IOC_MAXNR is 255, so this adds 2k to the stack frame just to allow the
printing of one of five ioctl names in a debug message.  It could be made
static ...
