2007-08-22cfag12864b fixMiguel Ojeda1-1/+1
This one-liner patch fixes a bug in drivers/auxdisplay/cfag12864b.c At cfag12864b_init(), the driver tries to kalloc some memory in the variable cfag12864b_cache. Then, as usual, it checks if the call failed. However, it checks cfag12864b_buffer instead. This patch changes the "cfag12864b_buffer" to "cfag12864b_cache" so the correct variable is checked.

2007-07-16Use menuconfig objects II - auxdisplayJan Engelhardt1-2/+6
Make a "menuconfig" out of the Kconfig objects "menu, ..., endmenu", so that the user can disable all the options in that menu at once instead of having to disable each option separately.

2007-06-01cfag12864bfb: Use sys_ instead of cfb_ framebuffer accessorsAvuton Olrich2-3/+9
Because the framebuffer memory is allocated system RAM, use the sys_ drawing libraries. It also fixes the following compile error: LD .tmp_vmlinux1 drivers/built-in.o:(.data+0x8b48): undefined reference to `cfb_fillrect' drivers/built-in.o:(.data+0x8b50): undefined reference to `cfb_copyarea' drivers/built-in.o:(.data+0x8b58): undefined reference to `cfb_imageblit' [adaplas] Use fb_sys_read/write for the same reasons as above.

2007-02-20[PATCH] cfag12864b: fix crash when built-in and no parport presentMiguel Ojeda3-1/+40
The problem comes when ks0108/cfag12864b are built-in and no parallel port is present. ks0108_init() is called first, as it should be, but fails to load (as there is no parallel port to use). After that, cfag12864b_init() gets called, without knowing anything about ks0108 failed, and calls ks0108_writecontrol(), which dereferences an uninitialized pointer. Init order is OK, I think. The problem is how to stop cfag12864b_init() being called if ks0108 failed to load. modprobe does it for us, but, how when built-in?
