The dmc520 driver requires that at least one interrupt line, out of the
ten possible, is configured. The driver prints an error and returns
-EINVAL from its .probe function if there are no interrupt lines
configured.
Don't print a KERN_ERR level message for each interrupt line that's
unconfigured as that can confuse users into thinking that there is an
error condition.
Before this change, the following KERN_ERR level messages would be
reported if only dram_ecc_errc and dram_ecc_errd were configured in the
device tree:
dmc520 68000000.dmc: IRQ ram_ecc_errc not found
dmc520 68000000.dmc: IRQ ram_ecc_errd not found
dmc520 68000000.dmc: IRQ failed_access not found
dmc520 68000000.dmc: IRQ failed_prog not found
dmc520 68000000.dmc: IRQ link_err not
dmc520 68000000.dmc: IRQ temperature_event not found
dmc520 68000000.dmc: IRQ arch_fsm not found
dmc520 68000000.dmc: IRQ phy_request not found
