Subject: liquidio: moved ptp_enable to octeon_device structure
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=aa69ff9e9c32db8aa84835baffea1b70c39e5112;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

liquidio: moved ptp_enable to octeon_device structure

ptp_enable was a global static variable.  Moved this global variable to
octeon_device structure and removed extra device id check.
