cfag12864b fix
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.
