Description

There are several "critical" functions that should normally cause probe() to return nonzero value in case of unsuccessful call. Possible examples are dma_set_mask and usb_register_dev.
Sample commit in linux_stable fixing error handling for dma_set_mask: eb9a2a9.

Updated by Vitaly Mordan about 10 years ago

Unnecessary headers
#include <linux/usb.h>
#include <linux/netdevice.h>
may cause Aspectator to failed at 'instrumentation' stage (for example, module drivers/media/usb/gspca/gspca_main.ko, kernel 3.16-rc1).

Updated by Vitaly Mordan about 10 years ago

Unnecessary semicolon in define:
around: define(usb_register(driver)) {
ldv_usb_register();
}
This causes Aspectator to failed, for example, at 'drivers/usb/core/usbcore.ko' module.
