Subject: [PATCH 1/3][staging-next] staging: pi433: Make a couple of functions static

From: Colin Ian King <colin.king@...onical.com>

The functions pi433_receive and pi433_tx_thread are local to the source
and do not need to be in global scope, so make them static

Cleans up sparse warnings:
symbol 'pi433_receive' was not declared. Should it be static?
symbol 'pi433_tx_thread' was not declared. Should it be static?
