It also helps avoid git merge to properly resolve two additions of the same member (possibly with a conflict) rather than just adding both.

Ah yes that makes a lot of sense. I will send a V2 in a moment, as the line I removed now means that it's not in order with the structure definition. regards, Peter.

.set_uhs_signaling field is currently initialised twice once to the arch specific callback pxav3_set_uhs_signaling, and also to the generic sdhci_set_uhs_signaling callback. This means that uhs is currently broken for this platform currently, as pxav3 has some special constriants which means it can't use the generic callback. This happened in commit 96d7b78cfc2f ("mmc: sdhci: convert sdhci_set_uhs_signaling() into a library function") commit a702c8abb2a9 ("mmc: host: split up sdhci-pxa, create sdhci-pxav3.c")' Signed-off-by: Peter Griffin <peter.griffin@linaro.org> --- drivers/mmc/host/sdhci-pxav3.c | 1 - 1 file changed, 1 deletion(-)
