Subject: NFC: nci: export nci_core_reset and nci_core_init
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=025a0cb8380b7100d39fb426db9192b6c59595dc;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

NFC: nci: export nci_core_reset and nci_core_init

Some drivers needs to have ability to reinit NCI core, for example
after updating firmware in setup() of post_setup() callback. This
patch makes nci_core_reset() and nci_core_init() functions public,
to make it possible.
