As Jiri requested, the staging fixes as a separate commit. I'll repost the non-staging changes as a separate commit also.
Cheers,
Ralph.
staging: Fix some incorrect use of positive error codes.
Use -E... instead of just E... in a few places where negative error
codes are expected by a functions callers. These were found by grepping
with coccinelle & then inspecting by hand to determine which were bugs.
The staging/cxt1e1 driver appears to intentionally use positive E...
error codes in some places, and negative -E... error codes in others,
making it hard to know which is intended where - very likely I missed
some problems in that driver.
