The return type of # free_percpu_irq() is 'void', while free_irq() returns a 'const void *' # that is the devname argument passed in to the request_irq(). # # You can't mix a void type with a non-void types in a conditional # expression according to the C standard. It so happens that gcc seems to # accept it - and the resulting type of the expression is void - but # there's really no reason for the kernel to have this kind of # non-standard expression with no real upside. # # The natural way to write that expression is with an if-statement: # # if (of_irq->percpu) # free_percpu_irq(of_irq->irq, clkevt); # else # free_irq(of_irq->irq, clkevt); # # which is more legible anyway. # # I'm not sure why that timer-of code seems to have this odd pattern. It # does the same at allocation time, but at least there the types match, # and it makes sense as an expression. # # Reported-by: Randy Dunlap <rdunlap@infradead.org> # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 0f1a7b3fac0583083ca19d4de47403511ced3521 # < make -s -j 8 ARCH=powerpc O=/kisskb/build/linus-rand_powerpc-randconfig_powerpc-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- randconfig KCONFIG_SEED=0x28EF000E # Added to kconfig CONFIG_STANDALONE=y # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # Added to kconfig CONFIG_CPU_BIG_ENDIAN=y # Added to kconfig CONFIG_PPC64=y # Added to kconfig CONFIG_PPC_DISABLE_WERROR=y # Added to kconfig CONFIG_SECTION_MISMATCH_WARN_ONLY=y # Added to kconfig CONFIG_PREVENT_FIRMWARE_BUILD=y # Added to kconfig CONFIG_CC_STACKPROTECTOR_STRONG=n # Added to kconfig CONFIG_GCC_PLUGINS=n # Added to kconfig CONFIG_LD_HEAD_STUB_CATCH=y # Added to kconfig CONFIG_TRIM_UNUSED_KSYMS=n # Added to kconfig CONFIG_UBSAN=n # yes \n | make -s -j 8 ARCH=powerpc O=/kisskb/build/linus-rand_powerpc-randconfig_powerpc-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- oldconfig yes: standard output: Broken pipe # make -s -j 8 ARCH=powerpc O=/kisskb/build/linus-rand_powerpc-randconfig_powerpc-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- In file included from /kisskb/src/arch/powerpc/xmon/xmon.c:63: /kisskb/src/arch/powerpc/xmon/dis-asm.h: In function 'print_insn_powerpc': /kisskb/src/arch/powerpc/xmon/dis-asm.h:16:13: warning: format '%x' expects argument of type 'unsigned int', but argument 2 has type 'long unsigned int' [-Wformat=] printf("%.8x", insn); ~~~^ ~~~~ %.8lx /kisskb/src/arch/powerpc/xmon/dis-asm.h: In function 'print_insn_spu': /kisskb/src/arch/powerpc/xmon/dis-asm.h:22:13: warning: format '%x' expects argument of type 'unsigned int', but argument 2 has type 'long unsigned int' [-Wformat=] printf("%.8x", insn); ~~~^ ~~~~ %.8lx /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld: warning: orphan section `.gnu.hash' from `linker stubs' being placed in section `.gnu.hash'. /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld: warning: orphan section `.gnu.hash' from `linker stubs' being placed in section `.gnu.hash'. /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld: warning: orphan section `.gnu.hash' from `linker stubs' being placed in section `.gnu.hash'.
