SubjectRe: [PATCH v2] mfd: cros: Update EC protocol to match current EC code
From
Date
Hi Gwendal,

Unless my pwclient or patchwork is doing something weird I have some issues
trying to apply this patch. Could you check that is correctly formatted?

$ pwclient git-am 1055029

Applying patch #1055029 using u'git am'
Description: [v2] mfd: cros: Update EC protocol to match current EC code
Applying: mfd: cros: Update EC protocol to match current EC code
error: patch fragment without header at line 11: @@ -105,15 +120,24 @@
Patch failed at 0001 mfd: cros: Update EC protocol to match current EC code
hint: Use 'git am --show-current-patch' to see the failed patch
When you have resolved this problem, run "git am --continue".
If you prefer to skip this patch, run "git am --skip" instead.
To restore the original branch and stop patching, run "git am --abort".
'git am' failed with exit status 128

Also if I try to apply the patch directly I got:

$ git am --show-current-patch | patch -p1

Complains about this malformed line, but even after fix this I got other issues.

Thanks,
