It sound like all return value in probe() is fixed.
Please reword this commit message like this:
spi: spi-fsl-qspi: Fix return value check of devm_ioremap() in probe()
>
> In case of error, the function devm_ioremap() returns NULL pointer not
> ERR_PTR(). The IS_ERR() test in the return value check should be replaced
> with NULL test.

> AHB buffer size")
