According to the dt-bindings, the default value of reg-io-width is 4. However, the value becomes zero when reg-io-width isn't specified. Should set the actual value to dws->reg_io_width, considering it referenced. Signed-off-by:

Merge series from Yang Yingliang <yangyingliang@huawei.com>: After introducing devm_spi_alloc_host/spi_alloc_host(), the legacy named function devm_spi_alloc_master/spi_alloc_master() can be replaced. And also change other legacy name master/slave to modern name host/target or controller.

In struct mpc52xx_psc_spi, the variable 'irq' is declared as an unsigned int. The comparison of variable 'irq' with signed int operand is incorrect. Also, the return value from the call to platform_get_irq(pdev,0) is int and it is assigned to an unsigned int variable 'irq', thus redeclaring the type of variable 'irq' to signed int. This fixes warning such as: drivers/spi/spi-mpc52xx-psc.c:332:5-13: WARNING: Unsigned expression compared with zero: mps -> irq < 0 Signed-off-by:

There is two warnings reported by coccinelle: ./drivers/spi/spi-mpc512x-psc.c:493:5-13: WARNING: Unsigned expression compared with zero: mps -> irq < 0 ./drivers/spi/spi-mpc52xx-psc.c:332:5-13: WARNING: Unsigned expression compared with zero: mps -> irq < 0 The commit "208ee586" ("spi: mpc5xxx-psc: Return immediately if IRQ resource is unavailable") was to check whether the IRQ resource is unavailable. When the IRQ resource is unavailable, an error code is returned, however, the type of "mps->irq" is "unsigned int", causing the error code to flip. Modify the type of "mps->irq" to solve this problem. Fixes: 208ee586 ("spi: mpc5xxx-psc: Return immediately if IRQ resource is unavailable") Signed-off-by:
