This function escapes certain special characters like \n. So if the
last character in the string is a '\n' then it gets changed into two
characters '\' and '\n'. But maybe we only have space for the '\' so
we need to check for that.
The "conv_dst_size" variable is always less than or to equal the "size"
variable. It's easier to just check "conv_dst_size" instead of checking
both.

The error handling won't work if "mid" is unsigned. "ret" is used to
store negative error codes and declaring it as a u32 won't cause a bug
but it's ugly. The "actual_outsize" variable is a number between 0-4096
so it can be declared as int as well.

Previously, some support for certain keys on the HP keyboard has been
added already in commit 3ee5447b20 ("platform/x86: hp-wmi: Handle Omen
Key event"), however this as tested did not allow even the fn+esc key on
my HP Envy which uses the same keycode on my HP Envy x360 laptop to work
--the keycode rather than being passed in as a separate int from WMI, was
being passed in as the event_data for the HPWMI_OMEN_KEY event.
This patch, as tested was able to properly get the keycode for fn+esc,
and for fn+f12 which is supposed to be a programmable key according to
HP's keyboard diagram and is thus mapped to KEY_PROG2. The fn+f8 key
combination (mute microphone) was a standard HPWMI_BEZEL_BUTTON key,
however it did not previously have an entry in the sparse keymap. This
patch preserves the original HPWMI_OMEN_KEY behavior for laptops that
use it by only taking the keycode from the event_data only when the
event_data is nonzero.

Previously, when the camera toggle switch was hit, the hp-wmi driver
would report an invalid event code. By adding a case for that in the
event handling switch statement we can eliminate that error code and
enable a framework for potential further kernel handling of that key.
This change was tested on my HP Envy x360 15-ey0023dx laptop, but it
would likely work for any HP laptop with a camera toggle button. Now
we emit an SW_CAMERA_LENS_COVER event, on a device that gets created
on the first such event so as to not report incorrectly the state of
the camera shutter before we can know its state.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is (mostly) ignored
and this typically results in resource leaks. To improve here there is a
quest to make the remove callback return void. In the first step of this
quest all drivers are converted to .remove_new() which already returns
void.
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.
