[PATCH AUTOSEL 5.15 1/3] tool api fs: Correctly encode errno for read/write open failures
From: Ian Rogers irogers@google.com
[ Upstream commit 05be17eed774aaf56f6b1e12714325ca3a266c04 ]
Switch from returning -1 to -errno so that callers can determine types of failure.

The F11 key on the new Lenovo Thinkpad T14 Gen 5, T16 Gen 3, and P14s Gen 5 laptops includes a symbol showing a smartphone and a laptop chained together. According to the user manual, it starts the Microsoft Phone Link software used to connect to Android/iOS devices and relay messages/calls or sync data.
As there are no suitable keycodes for this action, introduce a new one.

On the Acer Swift SFG14-41, the events 8 - 1 and 8 - 0 are printed on AC connect/disconnect. Ignore those events to avoid spamming the kernel log with error messages.
