Re: [PATCH v5 1/2] staging: iio: adc: ad7816: Serialize SPI read operations

[nasser]

Hi Joshua,

Thank you very much for your continuous guidance and patience with my
patches. I truly appreciate your feedback.

You are completely right. I mistakenly thought I could clean up and
sort the headers alongside the mutex addition without needing to
isolate it in a separate patch. I also apologize for letting the
`sizeof(buf)` change slip into the mutex patch.

I will prepare a v6 series shortly where I will:
1. Add a separate precursor patch solely for sorting and cleaning up
the headers.
2. Keep the mutex patch strictly focused on serializing the read
operations (adding only <linux/mutex.h> and <linux/cleanup.h>).
3. Move the `sizeof()` argument change to the DMA buffer patch where
it logically belongs.

Thanks again for pointing these out.

Best regards,
Abdelnasser
