The IrNET identation patch was too big for netdev limit, so I split it
in 2 patches:
[PATCH 1a/6] IrDA: IrNET code identation
[PATCH 1b/6] IrDA: irnet_irda.c identation
My apologies for the mess...
Cheers,
Samuel.

This is a split of: "[PATCH 1/6] IrDA: IrNET code indentation" for fitting
with netdev mail size limit.
The IrNET code was not exactly following the kernel coding style...
No functional changes, just an indentation fix.

This is a split of: "[PATCH 1/6] IrDA: IrNET code indentation" for fitting
with netdev mail size limit.
The IrNET code was not exactly following the kernel coding style...
No functional changes, just an indentation fix.
