[PATCH 0/2] staging: fix W=1 format-truncation warnings

by Masaharu Noguchi

- This series fixes -Wformat-truncation warnings in staging drivers found with W=1 builds: - greybus: prefix device id to widget/control names safely - vc04_services/bcm2835-camera: compose V4L2 bus_info safely Both changes use scnprintf() for the prefix and strscpy() for the remainder. No functional change intended.

[PATCH 6.15 088/480] staging: greybus: gbphy: fix up const issue with the match callback

by Greg Kroah-Hartman

6.15-stable review patch. If anyone has any objections, please let me know. ------------------ From: Greg Kroah-Hartman <gregkh(a)linuxfoundation.org> [ Upstream commit ce32eff1cf3ae8ac2596171dd0af1657634c83eb ] gbphy_dev_match_id() should be taking a const pointer, as the pointer passed to it from the container_of() call was const to start with (it was accidentally cast away with the call.) Fix this all up by correctly marking the pointer types.
