Enable Bluetooth support on Intel Edison
config: x86_64-randconfig-s4-04030434 (attached as .config)
compiler: gcc-6 (Debian 6.2.0-3) 6.2.0 20160901
reproduce:
git checkout d4d969909bef4c1e103eec0fc2c820773811fb72
# save the attached .config to linux build tree
make ARCH=x86_64
All errors (new ones prefixed by >>):
arch/x86/built-in.o: In function `tng_bt_sfi_setup':
platform_bt.c:(.init.text+0x13a30): undefined reference to
`gpiod_add_lookup_table'
I'd guess it's a missing dependency on GPIOLIB
Apparently not this one.
The module is purely built whenever HCIUART_BCM is defined which is a
consumer of GPIO.
And that one does not have a dependency.
Fengguang, this is second semi-false positive report. Can we do
something about such?
Andy, I didn't look into the logical side of this problem, however I
can reproduce the issue in commit d4d969909. While its parent commit
succeeded in producing the kernel:
