Subject: [PATCH] ptp: add max_phase_adj field and update rsv field of struct
 ptp_clock_caps

* bundled/linux/include/uapi/linux/ptp_clock.h (struct ptp_clock_caps):
Add max_phase_adj field and update rsv field following the change
introduced by Linux kernel commit v6.5-rc1~163^2~65^2~4.
* src/ptp.c (ptp_ioctl): Likewise.
* tests/ioctl_ptp.c (test_no_device): Update expected output.
