Since kernel 4.15, setup_timer is no more available and compilation fails with : make -C kernel make[1]: Entering directory '/.../wr-starting-kit/spec-sw/kernel' make -C /lib/modules/4.18.0-1-amd64/build M=/.../wr-starting-kit/spec-sw/kernel FMC_BUS_ABS=/.../wr-starting-kit/spec-sw/fmc-bus modules make[2]: Entering directory '/usr/src/linux-headers-4.18.0-1-amd64' CC [M] /.../wr-starting-kit/spec-sw/kernel/wr_nic/endpoint.o /.../wr-starting-kit/spec-sw/kernel/wr_nic/endpoint.c: In function 'wrn_ep_open': /.../wr-starting-kit/spec-sw/kernel/wr_nic/endpoint.c:193:2: error: implicit declaration of function 'setup_timer'; did you mean 'del_timer'?

For kernel > 4.15 timer_setup is use instead of setup_timer and callback is adapted to the new need. Signed-off-by: Gwenhael Goavec-Merou <gwenhael.goavec-merou@trabucayre.com>
