Subject: Fix kernel/softirq.c printk format warning properly
X-Git-Tag: firefly_0821_release~17378
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=1c95e1b69073cff5ff179e592fa1a1e182c78a17;p=firefly-linux-kernel-4.4.55.git

Fix kernel/softirq.c printk format warning properly

This fixes the broken 77af7e3403e7314c47b0c07fbc5e4ef21d939532
("softirq, warning fix: correct a format to avoid a warning") fix
correctly.

The type of a pointer subtraction is not "int", nor is it "long".  It
can be either (or something else).  It's "ptrdiff_t", and the printk
format for it is "%td".
