X-Git-Tag: v2.6.21-rc1~274^2~163
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ddc1e9753106cedcca7944d2b068baa2e14640b1;p=linux-2.6

[PATCH] spi: remove return in spi_unregister_driver()

Make the spi_unregister_driver() code fit in with the rest of the header
file, and only do the action if the driver passed is non-NULL.

This also makes the code a line smaller.
