5.4-stable review patch. If anyone has any objections, please let me know. ------------------ From: Dmitry Antipov <dmantipov@xxxxxxxxx> [ Upstream commit e64285ff41bb7a934bd815bd38f31119be62ac37 ] Since '1 << rocker_port->pport' may be undefined for port >= 32, cast the left operand to 'unsigned long long' like it's done in 'rocker_port_set_enable()' above. Compile tested only. Found by Linux Verification Center (linuxtesting.org) with SVACE.
