Subject: staging: nvec: specify a platform-device base id
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3ec698816ab3a7aca39dd3389115840a48d5266d;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

staging: nvec: specify a platform-device base id

commit 6e3f62f079 (mfd: core: Fix platform-device id generation) modified
the computation of the mfd cell id. Negative numbers forbit the specification
of cell ids as we do. Fix this for now by specifying a base of 0 instead. In
the long run, this may be changed to automatic cell ids (base -2).
