[PATCH 4.14 243/496] can: m_can: change comparison to bitshift when dealing with a mask

[Greg Kroah-Hartman]

4.14-stable review patch.  If anyone has any objections, please let me know.

From: Wolfram Sang <wsa+renesas@xxxxxxxxxxxxxxxxxxxx>

[ Upstream commit b7db978ac283b237835129ac87f26cbac94d04e7 ]

Due to a typo, the mask was destroyed by a comparison instead of a bit
shift.
