[PATCH 05/11v2] ata: replace macro with static inline in libata.h

From: Harvey Harrison
Date: Thu Feb 14 2008 - 13:11:56 EST


Instead of using min/max_t(short... use a static inline to get
typechecking.

As a bonus, avoid a metric ton of sparse warnings like:
drivers/ata/pata_ali.c:176:14: warning: symbol '__x' shadows an earlier one
drivers/ata/pata_ali.c:176:14: originally declared here

Due to nesting min_t macro inside max_t macro which both use a __x
identifier internally.
