1) Make your subject line match the history. For example, you're
fixing 769e49d87b15 ("PCI: qcom: Sort and group registers ..."), so
your subject line should start with "PCI: qcom: ...".
2) It doesn't look like 769e49d87b15 changed
PARF_SLV_ADDR_SPACE_SIZE_2_3_3:
$ git show 769e49d87b15 | grep PARF_SLV_ADDR_SPACE_SIZE_2_3_3
+#define PARF_SLV_ADDR_SPACE_SIZE_2_3_3 0x16C /* Register offset specific to IP ver 2.3.3 */
-#define PARF_SLV_ADDR_SPACE_SIZE_2_3_3 0x16C /* Register offset specific to IP rev 2.3.3 */
What am I missing here? Do you have another out-of-tree patch that
broke this?
