Subject: isdn: Make CONFIG_ISDN depend on CONFIG_NETDEVICES
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=7fd78edc470d968daacfb472226bc021081196bd;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

isdn: Make CONFIG_ISDN depend on CONFIG_NETDEVICES

It doesn't make much sense to enable ISDN services if you don't
intend to connect to a network. Therefore insisting that ISDN
depends on NETDEVICES seems logical. We can then remove any
guards mentioning NETDEVICES inside all subordinate drivers.

This also has the nice side-effect of fixing the warning below
when ISDN_I4L && !CONFIG_NETDEVICES at compile time.

This patch fixes:
drivers/isdn/i4l/isdn_common.c: In function ‘isdn_ioctl’:
drivers/isdn/i4l/isdn_common.c:1278:8: warning: unused variable ‘s’ [-Wunused-variable]
