Subject: spi: bcm2835: Make polling_limit_us static
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=50851f5033a34fb9f2ecefa57fc9efd862634416;p=linux.git

spi: bcm2835: Make polling_limit_us static

This eliminates the following sparse warning:

drivers/spi/spi-bcm2835.c:78:14: warning: symbol 'polling_limit_us' was
not declared. Should it be static?
