Subject: [PATCH RFC] irda: condition with no effect

The if and the else branch code are identical - so the condition has no
effect on the effective code - this patch removes the condition and the
duplicated code.

As the if and else is functionally identical they could probably be
joined. From the comments it does seem that they might need to be
different cases - which could mean there is a bug here - someone that
knows the details of the drivers will need to check.

Joined the comments on the modes - which also might not be correct.

Note: this gives some warnings on CamelCase usage - but those are not
related to the proposed changes.

Patch was only compile tested for x86_64_defconfig + CONFIG_IRDA=m
CONFIG_VIA_FIR=m

Patch is against 3.19.0-rc7 (localversion-next = -next-20150203)
