Ander Conselvan de Oliveira 5b7280f03c drm/i915/glk: Fix maximum scaling factor for Geminilake scalers ... Geminilake can output two pixels per clock, and that affects the maximum scaling factor for its scalers. Take that into account and avoid the following warning: WARNING: CPU: 1 PID: 593 at drivers/gpu/drm/i915/intel_display.c:13223 skl_max_scale.part.129+0x78/0x80 [i915] WARN_ON_ONCE(!crtc_clock || cdclk < crtc_clock) Modules linked in: x86_pkg_temp_thermal i915 coretemp kvm_intel kvm i2c_algo_bit drm_kms_helper irqbypass crct10dif_pclmul prime_numbers crc32_pclmul drm ghash_clmulni_intel shpchp tpm_tis tpm_tis_core tpm nfsd authw CPU: 1 PID: 593 Comm: kworker/u8:3 Tainted: G W 4.10.0-rc8ander+ #330 Hardware name: Intel Corp.
