Takashi Iwai b897f1dc78 ASoC: skl: Fix kernel warning due to zero NHTL entry ... commit 20a1ea2222 upstream. I got the following kernel warning when loading snd-soc-skl module on Dell Latitude 7270 laptop: memremap attempted on mixed range 0x0000000000000000 size: 0x0 WARNING: CPU: 0 PID: 484 at kernel/memremap.c:98 memremap+0x8a/0x180 Call Trace: skl_nhlt_init+0x82/0xf0 [snd_soc_skl] skl_probe+0x2ee/0x7c0 [snd_soc_skl] .... It seems that the machine doesn't support the SKL DSP gives the empty NHLT entry, and it triggers the warning. For avoiding it, let do the zero check before calling memremap().
