2021-01-18pinctrl: ingenic: Only support SoCs enabled in configPaul Cercueil1-12/+48
Tested on a JZ4740 system (ARCH=mips make qi_lb60_defconfig), this saves about 14 KiB, by allowing the compiler to garbage-collect all the functions and tables that correspond to SoCs that were disabled in the config.

2021-01-18kconfig.h: Add IF_ENABLED() macroPaul Cercueil1-0/+6
IF_ENABLED(CONFIG_FOO, ptr) evaluates to (ptr) if CONFIG_FOO is set to 'y' or 'm', NULL otherwise. The (ptr) argument must be a pointer. The IF_ENABLED() macro can be very useful to help GCC drop dead code. For instance, consider the following: #ifdef CONFIG_FOO_SUSPEND static int foo_suspend(struct device *dev) { ... } #endif static struct pm_ops foo_ops = { #ifdef CONFIG_FOO_SUSPEND .suspend = foo_suspend, #endif }; While this works, the foo_suspend() macro is compiled conditionally, only when CONFIG_FOO_SUSPEND is set. This is problematic, as there could be a build bug in this function, we wouldn't have a way to know unless the config option is set. An alternative is to declare foo_suspend() always, but mark it as maybe unused: static int __maybe_unused foo_suspend(struct device *dev) { ... } static struct pm_ops foo_ops = { #ifdef CONFIG_FOO_SUSPEND .suspend = foo_suspend, #endif }; Again, this works, but the __maybe_unused attribute is required to instruct the compiler that the function may not be referenced anywhere, and is safe to remove without making a fuss about it. This makes the programmer responsible for tagging the functions that can be garbage-collected. With this patch, it is now possible to write the following: static int foo_suspend(struct device *dev) { ... } static struct pm_ops foo_ops = { .suspend = IF_ENABLED(CONFIG_FOO_SUSPEND, foo_suspend), }; The foo_suspend() function will now be automatically dropped by the compiler, and it does not require any specific attribute.

When DEBUG is defined (e.g. if CONFIG_DEBUG_PINCTRL=y), the Renesas pin control driver runs sanity checks against the pin control tables. This may cause lots of output on the console, and can be annoying in ARM multi-platform kernels. Fix this by only running the checks when running on SuperH, or on a DT platform supported by the Renesas pin controller driver.

As there is an RSB controller in the H6 SoC, there should be some pin configuration for it. While no such configuration is documented, the "s_i2c" pins are suspiciously on the "alternate" function 3, with no primary function 2 given. This suggests the primary function for these pins is actually RSB, and that is indeed the case. Add the "s_rsb" pin functions so the RSB controller can be used.

Since commit 36e2c7421f02 ("fs: don't allow splice read/write without explicit ops") we've required that file operation structures explicitly enable splice support, rather than falling back to the default handlers. Most /proc files use the indirect 'struct proc_ops' to describe their file operations, and were fixed up to support splice earlier in commits 40be821d627c..b24c30c67863, but the mountinfo files interact with the VFS directly using their own 'struct file_operations' and got missed as a result. This adds the necessary support for splice to work for /proc/*/mountinfo and friends.

2020-12-26mfd: ab8500-debugfs: Remove extraneous seq_putcLinus Torvalds1-1/+0
Commit c9a3c4e637ac ("mfd: ab8500-debugfs: Remove extraneous curly brace") removed a left-over curly brace that caused build failures, but Joe Perches points out that the subsequent 'seq_putc()' should also be removed, because the commit that caused all these problems already added the final '\n' to the seq_printf() above it.

2020-12-26PCI: dwc: Fix inverted condition of DMA mask setup warningAlexander Lobakin1-6/+2
Commit 660c486590aa ("PCI: dwc: Set 32-bit DMA mask for MSI target address allocation") added dma_mask_set() call to explicitly set 32-bit DMA mask for MSI message mapping, but for now it throws a warning on ret == 0, while dma_set_mask() returns 0 in case of success. Fix this by inverting the condition.
