2022-04-19EDAC/dmc520: Don't print an error for each unconfigured interrupt lineTyler Hicks
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 Petkov
dimm->edac_mode contains values of type enum edac_type - not the corresponding capability flags. Fix that.
