[2.6 patch] drivers/mtd/mtdcore.c: less PROC_FS=n #ifdef's

[Adrian Bunk]

I'm surprised that kill-ifdefs-in-mtdcorec.patch in -mm that removes
#ifdef's for the PROC_FS=n case wasn't tested with PROC_FS=n...

<--  snip  -->

...

<--  snip  -->


The patch below tries to do it in a correct way.

This patch reduces the number of #ifdef's for CONFIG_PROC_FS=n.
