>+ supported = !read_ec_cmd(ideapad_handle, VPCCMD_R_FAN, &value); I'm sorry, there is a typo, this line should look like this: + supported = !read_ec_data(ideapad_handle, VPCCMD_R_FAN, &value); Here is the latest version of the patch: http://paste.ubuntu.com/1006185/ Didn't send it in letter body, because it's mostly the same as previous. So what about the patch? -- To unsubscribe from this list: send the line "unsubscribe platform-driver-x86" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
