Subject: staging: Fix some incorrect use of positive error codes.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3ec6080e2e5be05e6f7fbbe5ab20b0eab84e166b;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

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.
