Subject: spi: sprd: Simplify with dev_err_probe()
X-Git-Tag: v5.10-rc1~172^2^2~67
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=9d99e55833dddf76dd6470e7ce97201abb612c03;p=thirdparty%2Fkernel%2Flinux.git

spi: sprd: Simplify with dev_err_probe()

Common pattern of handling deferred probe can be simplified with
dev_err_probe().  Less code and the error value gets printed.
