platform-drivers-x86 for v4.16-6
Correct a module loading race condition between the DELL_SMBIOS backend modules and the first user by converting them to bool features of the DELL_SMBIOS driver. Fixup the resulting Kconfig dependency issue with DCDBAS. The following is an automated git shortlog grouped by driver: - Resolve dependency error on DCDBAS - Allow for SMBIOS backend defaults - Link all dell-smbios-* modules together - Rename dell-smbios source to dell-smbios-base - Correct some style warnings -----BEGIN PGP SIGNATURE----- iQEcBAABAgAGBQJaot3AAAoJEKbMaAwKp364dmgIAIfHTsJK43WBdhiA8t+ZR2eI vW6gWOmTR0srhybgBFh+yNd0ljH4Ogb/JUrFuF6cemtpWxTJC+KS0gZWbHFw/5w5 OsovY0/8AVtC7IFVe0HH3w3fZwsGGq4H/LU1K580cRF/YYzMVXnr2ASkIqn/EUzS voeAuL23JYvq+ByAqqKmA3tN7/+YpMrt5MPkJHk/MGnGxspTapcMvEK/fkYSlDWa MpWuKWqfFMM02sV37zyNQYaU64+5/FtGL/2OwsuMD6OgCism+FS/gPhR1JYLtPbd GKJoSfWqn2cMnLTA+1V9ya0zvGAwK4AdIoe4Cjg49pITXZneNfw+NzoQUe12Yg4= =FAX7 -----END PGP SIGNATURE----- Merge tag 'platform-drivers-x86-v4.16-6' of git://git.infradead.org/linux-platform-drivers-x86 Pull x86 platform driver fixes from Darren Hart: "Correct a module loading race condition between the DELL_SMBIOS backend modules and the first user by converting them to bool features of the DELL_SMBIOS driver.
