[PATCH] drivers/acpi: Add and use pr_fmt(fmt)

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Use #define pr_fmt(fmt) with appropriate prefix.
Remove use PREFIX/<foo>_PFX from pr_<level>.
Remove #defines of PREFIX and <foo>_PFX.
Coalesce some formats.

This changes the output of messages that use FW_WARN/FW_BUG
so that the prefix is first then FW_<LEVEL>.
