[PATCH] evaluate getenv() return value for udev_config.c
Small patch to fix the evaluation logic for the return value of getenv() in udev_config.c file. Basically, the actual values for the environment variables "UDEV_NO_SLEEP" and "UDEV_NO_DEVD" were not being checked. For example UDEV_NO_SLEEP could have been set to false but the line: if (getenv("UDEV_NO_SLEEP") != NULL) in this case would always evaluate to true, since getenv() returns char*, thus the "udev_sleep" variable would be set incorrectly. The patch makes sure to check the value returned by getenv() not just if getenv() returned a value. Hope this made sense. Thanks,
