Let's tidy up a few things: - we can't send out one patch labelled as part of a patchset without resending the entire set. That's why I was suggesting just abandoning the patchset, and beginning to rework this anew with only the fbtft driver in a single patch. - I suggest keeping the -bus and -io file changes together. - Look to correct what is wrong with fbtft-bus.c before sending a new patch. - Patch Subject would be something like: use __be64 types for endian correctness (if this is what you end up doing - hint) So, next step, 1) read up on endianess and propose how to change -bus.c. OK to check that idea/code snippet here without re-rolling the patch. https://kernelnewbies.org/EndianIssues and Vaishali also gave a good link to lwn.net article and to see some example fixes (in iio subsystem) do this: git log --pretty=oneline --abbrev-commit | grep iio | grep endian 2) build the patch. At this point I say make it a first version and start totally fresh. However, below the line --- where you usually put the version comments, you can add a comment stating that this was previously part of a patchset, but is now a single patch. alisons > > drivers/staging/fbtft/fbtft-io.c | 2 +- > 1 file changed, 1 insertion(+), 1 deletion(-) > > diff --git a/drivers/staging/fbtft/fbtft-io.c b/drivers/staging/fbtft/fbtft-io.c > index d868405..ffb9a3b 100644 > --- a/drivers/staging/fbtft/fbtft-io.c > +++ b/drivers/staging/fbtft/fbtft-io.c > @@ -71,7 +71,7 @@ int fbtft_write_spi_emulate_9(struct fbtft_par *par, void *buf, size_t len) > src++; > } > tmp |= ((*src & 0x0100) ? 1 : 0); > - *(u64 *)dst = cpu_to_be64(tmp); > + *(__be64 *)dst = cpu_to_be64(tmp); > dst += 8; > *dst++ = (u8)(*src++ & 0x00FF); > added++; > -- > 2.7.4 > > -- > You received this message because you are subscribed to the Google Groups "outreachy-kernel" group. > To unsubscribe from this group and stop receiving emails from it, send an email to outreachy-kernel+unsubscribe@xxxxxxxxxxxxxxxx. > To post to this group, send email to outreachy-kernel@xxxxxxxxxxxxxxxx. > To view this discussion on the web visit https://groups.google.com/d/msgid/outreachy-kernel/20170305050533.GA10169%40singhal-Inspiron-5558. > For more options, visit https://groups.google.com/d/optout. _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
