2022-04-19EDAC/dmc520: Don't print an error for each unconfigured interrupt lineTyler Hicks1-1/+1
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 Fixes: 1088750d7839 ("EDAC: Add EDAC driver for DMC520") Reported-by: Sinan Kaya <okaya@kernel.org> Signed-off-by: Tyler Hicks <tyhicks@linux.microsoft.com> Signed-off-by: Borislav Petkov <bp@suse.de> Link: https://lore.kernel.org/r/20220111163800.22362-1-tyhicks@linux.microsoft.com
2021-09-16EDAC/dmc520: Assign the proper type to dimm->edac_modeBorislav Petkov1-1/+1
dimm->edac_mode contains values of type enum edac_type - not the corresponding capability flags. Fix that.
