From d424aa8744b7b7db1d32476ae6c8015d10eebe1c Mon Sep 17 00:00:00 2001 From: Jim Cromie Date: Tue, 27 Jun 2006 02:54:16 -0700 Subject: [PATCH] [PATCH] chardev: GPIO for SCx200 & PC-8736x: put gpio_dump on a diet Shrink scx200_gpio_dump() to a single printk with ternary ops. The function is still ifdef'd out, this is corrected in next patch, when it is actually used. The patch 'inadvertently' changed loglevel from DEBUG to INFO. This is Good, because in next patch, its wired to a 'command' which the user can invoke when they want. When they do so, its because they want INFO to support their developement effort, and we want to give it to them without compiling a DEBUG version of the driver.
