modpost: detect modules without a MODULE_LICENSE
Partially revert commit 2fa365682943 ("kbuild: soften MODULE_LICENSE check") so that modpost detects modules that do not have a MODULE_LICENSE. Sam's commit also changed the fatal error to a warning, which I am leaving as is. This gives advance notice of when a module has no license and will taint the kernel if the module is loaded. This produces the following warnings on x86_64 allmodconfig: MODPOST 6520 modules WARNING: modpost: missing MODULE_LICENSE() in drivers/auxdisplay/img-ascii-lcd.o WARNING: modpost: missing MODULE_LICENSE() in drivers/gpio/gpio-ath79.o WARNING: modpost: missing MODULE_LICENSE() in drivers/gpio/gpio-iop.o WARNING: modpost: missing MODULE_LICENSE() in drivers/iio/accel/kxsd9-i2c.o WARNING: modpost: missing MODULE_LICENSE() in drivers/iio/adc/qcom-vadc-common.o WARNING: modpost: missing MODULE_LICENSE() in drivers/media/platform/mtk-vcodec/mtk-vcodec-common.o WARNING: modpost: missing MODULE_LICENSE() in drivers/media/platform/soc_camera/soc_scale_crop.o WARNING: modpost: missing MODULE_LICENSE() in drivers/mtd/nand/denali_pci.o WARNING: modpost: missing MODULE_LICENSE() in drivers/net/phy/cortina.o WARNING: modpost: missing MODULE_LICENSE() in drivers/pinctrl/pxa/pinctrl-pxa2xx.o WARNING: modpost: missing MODULE_LICENSE() in drivers/power/reset/zx-reboot.o WARNING: modpost: missing MODULE_LICENSE() in drivers/rpmsg/qcom_glink_native.o WARNING: modpost: missing MODULE_LICENSE() in drivers/staging/comedi/drivers/ni_atmio.o WARNING: modpost: missing MODULE_LICENSE() in net/9p/9pnet_xen.o WARNING: modpost: missing MODULE_LICENSE() in sound/soc/codecs/snd-soc-pcm512x-spi.o Signed-off-by: Randy Dunlap <rdunlap@infradead.org> Cc: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
