pm8001_get_gsm_dump() was returning "1" in error case
instead of negative error code.

Hi,

the pm8001_get_gsm_dum return value is used here I think:
----------------
static ssize_t pm8001_ctl_gsm_log_show(struct device *cdev,
       struct device_attribute *attr, char *buf)
{
       u32 count;

       count = pm8001_get_gsm_dump(cdev, SYSFS_OFFSET, buf);
---------------
could you also change the 'count' from unsigned to a signed type?

Maybe in some cases another errno would make more sense (ENODEV, EIO?),
but I'll leave this up to you.

I have noticed in this series only patches 5/6 and 6/6, I miss the
1-4/6, could you help me find them ? What are the subjects of 1-4/6?

Thanks, Tomas

Hi Tomas,

Patches 1-4 are submitted with subject "[PATCH V2 0/4]: pm8001 driver bug fixes".

As this patch has to be applied after those four patches, we submitted this as 5/6 and 6/6.

We will resend the modified  patch.

Regards,
Viswas G

I was confused because the series 1-4/4 was send by another person,
thanks for clarification.

And it was labelled 1-4/4 so it's not really natural to think of 5 and 6
following on ... you weren't the only one confused.
