Hello!
Building kernel with following option should make brightness adjustment working on various Intel BayTrail-based devices such as HP Stream 7 Tablet, Microsoft Surface 3, and quite a few tablets from ASUS, and many no-name Chinese companies.
CONFIG_PWM_LPSS=y CONFIG_PWM_LPSS_PCI=y CONFIG_PWM_LPSS_PLATFORM=y
I tested this change on HP Stream 7, by installing Linux 4.18rc6 from http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.18-rc6/ and then installing same kernel, but with built in CONFIG_PWM_LPSS modules listed above.
