Hi all,

After merging the spi tree, today's linux-next build (x86_64 allmodconfig)
produced this warning:

drivers/spi/spi-hisi-kunpeng.c: In function 'hisi_spi_transfer_one':
drivers/spi/spi-hisi-kunpeng.c:361:9: warning: conversion from 'long unsigned int' to 'unsigned int' changes value from '18446744073709551600' to '4294967280' [-Woverflow]
361 | writel(~IMR_MASK, hs->regs + HISI_SPI_IMR);
| ^
