Subject: ptp: ocp: Make debugfs variables the correct bitwidth
X-Git-Tag: v6.6.17~7931^2~48
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=2b341f7532d4f6c8b84206daad202a745962b844;p=platform%2Fkernel%2Flinux-rpi.git

ptp: ocp: Make debugfs variables the correct bitwidth

An earlier patch mistakenly changed these variables from u32 to u16,
leading to unintended truncation.  Restore the original logic.

Fixes: a509a7c61e3b ("ptp: ocp: Add support for selectable SMA directions.")
