* fbdev: fix snprintf() limit in show_bl_curve()Dan Carpenter2015-09-01
| | | | | | | | | | | | The limit should be "PAGE_SIZE - len" instead of PAGE_SIZE. Also let's use scnprintf() because snprintf() returns the number of bytes which would have been printed if there were space and scnprintf() returns the number of bytes actually printed. I don't think we are ever going to actually hit this limit in real life. Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
* video: fbdev: use %*ph specifier to dump small buffersAndy Shevchenko2014-09-09
| | | | | | | | Instead of dereference each byte let's use %*ph specifier in the printk() calls. Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
* fbdev: move fbdev core files to separate directoryTomi Valkeinen2014-04-17
Instead of having fbdev framework core files at the root fbdev directory, mixed with random fbdev device drivers, move the fbdev core files to a separate core directory. This makes it much clearer which of the files are actually part of the fbdev framework, and which are part of device drivers.
