Hi all, After merging the mfd tree, today's linux-next build (powerpc allyesconfig) failed like this: drivers/regulator/max77686.c:432:13: warning: 'struct max77686_platform_data' declared inside parameter list struct max77686_platform_data *pdata) ^ drivers/regulator/max77686.c:432:13: warning: its scope is only this definition or declaration, which is probably not what you want drivers/regulator/max77686.c: In function 'max77686_pmic_dt_parse_pdata': drivers/regulator/max77686.c:447:7: error: dereferencing pointer to incomplete type pdata->num_regulators = ARRAY_SIZE(regulators); ^ drivers/regulator/max77686.c:448:42: error: dereferencing pointer to incomplete type rdata = devm_kzalloc(&pdev->dev, sizeof(*rdata) * ^ drivers/regulator/max77686.c:449:14: error: dereferencing pointer to incomplete type pdata->num_regulators, GFP_KERNEL); ^ drivers/regulator/max77686.c:455:23: error: dereferencing pointer to incomplete type for (i = 0; i < pdata->num_regulators; i++) { ^ drivers/regulator/max77686.c:460:3: error: invalid use of undefined type 'struct max77686_regulator_data' rdata[i].initdata = rmatch.init_data; ^ drivers/regulator/max77686.c:460:8: error: dereferencing pointer to incomplete type rdata[i].initdata = rmatch.init_data; ^ drivers/regulator/max77686.c:461:3: error: invalid use of undefined type 'struct max77686_regulator_data' rdata[i].of_node = rmatch.of_node; ^ drivers/regulator/max77686.c:461:8: error: dereferencing pointer to incomplete type rdata[i].of_node = rmatch.of_node; ^ drivers/regulator/max77686.c:464:7: error: dereferencing pointer to incomplete type pdata->regulators = rdata; ^ And so on ... Caused by commit 9d5f4c2c748e ("mfd: max77686/802: Remove support for board files") from the mfd tree. I reverted that commit for today. -- Cheers, Stephen Rothwell sfr@canb.auug.org.au
