The new tag 'emm' seems not suitable here, keep the original 'eclk' here, modify the upper 'eclk' tags instead:
...
ret = i2c_pxa_probe_dt(dev, i2c, &i2c_type);
if (ret > 0)
ret = i2c_pxa_probe_pdata(dev, i2c, &i2c_type);
if (ret < 0)
- goto eclk;
+ goto etype;
res = platform_get_resource(dev, IORESOURCE_MEM, 0);
irq = platform_get_irq(dev, 0);
if (res == NULL || irq < 0) {
ret = -ENODEV;
- goto eclk;
+ goto edev;
}
if (!request_mem_region(res->start, resource_size(res), res->name)) {
ret = -ENOMEM;
- goto eclk;
+ goto emem;
}
...
