Subject: [patch 6/7] drivers/net/sfc/falcon.c: fix min() warnings
From: Andrew Morton <akpm@...ux-foundation.org>
drivers/net/sfc/falcon.c: In function 'falcon_spi_write_limit':
drivers/net/sfc/falcon.c:1679: warning: comparison of distinct pointer types lacks a cast
drivers/net/sfc/falcon.c: In function 'falcon_spi_read':
drivers/net/sfc/falcon.c:1720: warning: comparison of distinct pointer types lacks a cast
Driver seems rather confused about types. Try to help it.
