Subject: efi: efivars: add efivars printk prefix
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=beeb107c5b354f4eaea17a9bca6ca8762f60effc;p=linux.git

efi: efivars: add efivars printk prefix

Add an 'efivars: ' printk prefix to make the log entries stand out more,
for example:

	efivars: Registered efivars operations

While at it, change the sole remaining direct printk() call to pr_err().
