SubjectRe: [PATCH 1/2] input: cyapa: fix sparse warning issue of incorrect type in assiggment
Dudley,

Mis-spelled 'assiggment' in Subject line.

I wasn't able to reproduce the sparse warning. Was it for a specific
architecture? Perhaps include a link to the email sent by the kbuild
test robot.

I don't think sparse cares about variable names.
Be sure to note these changes in your log.

I could be wrong but it looks there are a lot of changes un-related to
the sparse warning. I am not opposed to this per se but they should be
noted in the log message.
