Another nice thing to do is to use git format-patch --cover-letter
so that you can use a [PATCH 0/n] introductory description too.

Other than that, nice job, thanks.

Perhaps now you can do the "0x%u" variants.

$ /usr/bin/git grep -P '0x\%(?!ullx\b|ullX\b|llux\b|lux\b|ulx\b|ulX\b|lx\b|lluX\b|luX\b|lX\b)[ul]*[u]'
drivers/iommu/arm-smmu.c:                                   "Unexpected context fault (fsr 0x%u)\n",
drivers/net/vmxnet3/vmxnet3_drv.c:                              "txd[%u]: 0x%llu %u %u\n",
drivers/net/wireless/mwifiex/cfg80211.c:                wiphy_dbg(wiphy, "info: ongoing ROC, cookie = 0x%llu\n",
drivers/pinctrl/pinctrl-at91.c:         dev_dbg(dev, "pio%c%d configured as periph%c with conf = 0x%lu\n",
drivers/pinctrl/pinctrl-at91.c:         dev_dbg(dev, "pio%c%d configured as gpio with conf = 0x%lu\n",
drivers/scsi/cxgbi/libcxgbi.c:          "csk 0x%p,%u,0x%lu,%u, seq %u, wup %u, thre %u, %u.\n",
drivers/scsi/qla2xxx/qla_target.c:          "dif check TGT cdb 0x%x lba 0x%llu: [Actual|Expected] Ref Tag[0x%x|0x%x], App Tag [0x%x|0x%x], Guard [0x%x|0x%x]\n",
drivers/usb/musb/ux500_dma.c:           "packet_sz=%d, mode=%d, dma_addr=0x%llu, len=%d is_tx=%d\n",
fs/exofs/dir.c:         "offset=%lu, inode=0x%llu, rec_len=%d, name_len=%d\n",
fs/xfs/xfs_discard.c:    "discard failed for extent [0x%llu,%u], error %d",
sound/soc/atmel/atmel_ssc_dai.c:        pr_debug("atmel_ssc_startup: SSC_SR=0x%u\n",

There are some more with specific format lengths too:

arch/sparc/kernel/smp_32.c:             printk(KERN_NOTICE "No MID found for CPU%d at node 0x%08d", id, cpu_node);
drivers/mfd/rtsx_usb.c: dev_dbg(&intf->dev, "%s called with pm message 0x%04u\n",
drivers/net/wireless/rtlwifi/rtl8192de/fw.c:             "Polling FW ready fail!! REG_MCUFWDL:0x%08ul\n",
drivers/tty/moxa.c:                     printk(KERN_INFO "MOXA isa board found at 0x%.8lu and "

cheers, Joe
