Subject: hwrng: pixocel - Staticize 'rng_dev'
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=75be45683d5ff3f859f9cb2082574f96f8fd768f;p=linux-beck.git

hwrng: pixocel - Staticize 'rng_dev'

'rng_dev' is used only in this file.
Fix the following sparse warning:

drivers/char/hw_random/picoxcell-rng.c:36:15: warning: symbol 'rng_dev' was not declared. Should it be static?
