Subject: ata: Don't require newlines for link_power_management_policy
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=6a74463798bde03f849d8d82d97e4f8e4cf160f3;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

ata: Don't require newlines for link_power_management_policy

sysfs attributes shouldn't require newlines. Make it possible to set the
link power management policy without a trailing newline.
