Subject: devlink: Increase bus, device buffer size to 64 bytes
X-Git-Tag: v5.2.0~27
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=2cc10ce81d22676a3eff02dd57dd524828489449;p=thirdparty%2Fiproute2.git

devlink: Increase bus, device buffer size to 64 bytes

Device name on mdev bus is 36 characters long which follow standard uuid
RFC 4122.
This is probably the longest name that a kernel will return for a
device.

Hence increase the buffer size to 64 bytes.
