issue with driver.sh locally

[nickdesaulniers]

I ran

$ ./driver.sh ARCH=x86_64 LLVM=1 LLVM_IAS=1 REPO=android-mainline

locally, but when I cd common, I see it's on the wrong branch. android-4.9-q was checked out. But

+ git fetch --depth=1 https://android.googlesource.com/kernel/common android-mainline
remote: Total 0 (delta 0), reused 0 (delta 0)
From https://android.googlesource.com/kernel/common
 * branch                      android-mainline -> FETCH_HEAD
+ git reset --hard FETCH_HEAD
HEAD is now at 99be12b566d5 FROMLIST: arm64: vdso32: Allow ld.lld to properly link the VDSO
+ git show -s
+ cat
commit 99be12b566d557fa83764d28561ae87d3e1635e6
