From 6561863678822847be92c3bd06ae1d64acca4f6a Mon Sep 17 00:00:00 2001 From: Timur Tabi Date: Fri, 27 Aug 2010 15:45:47 -0500 Subject: [PATCH] video: cfb_console: fix definition and usage of CURSOR_xxx macros The CURSOR_ON, CURSOR_OFF, and CURSOR_SET macros are defined incorrectly. If cursor support is disabled, then these macros are defined to nothing, but then they are used like this: if (console_col < CONSOLE_COLS) CURSOR_OFF console_row++; which was compiled like this: if (console_col < CONSOLE_COLS) console_row++; This is obviously not what was intended.
