[PATCH 1/8] pseries/plpks: update PKS documentation and maintainer entry

From: Srish Srinivasan

Date: Thu Aug 27 2026 - 02:25:08 EST


Wrap long PKS hcall return-value lines consistently and fix a typo in the
H_PKS_UNWRAP_OBJECT description.

Also update the MAINTAINERS entry from KEYS-TRUSTED-PLPKS to
KEYS-TRUSTED-PKWM to reflect the PowerVM Key Wrapping Module naming.

Fixes: 133aa79e211d ("pseries/plpks: add HCALLs for PowerVM Key Wrapping Module")
Fixes: c99fcb0d735b ("keys/trusted_keys: establish PKWM as a trusted source")
