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/gcc-4.6.3-nolibc/mips-linux/bin/mips-linux-gcc --version # < /opt/cross/kisskb/gcc-4.6.3-nolibc/mips-linux/bin/mips-linux-ld --version # < git log --format=%s --max-count=1 0f1a7b3fac0583083ca19d4de47403511ced3521 # < make -s -j 8 ARCH=mips O=/kisskb/build/linus_mips-allmodconfig_mips CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/mips-linux/bin/mips-linux- allmodconfig # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # Added to kconfig CONFIG_SAMPLES=n # Added to kconfig CONFIG_MIPS_CPS_NS16550_BASE=0x1b0003f8 # Added to kconfig CONFIG_MIPS_CPS_NS16550_SHIFT=0 # yes \n \| make -s -j 8 ARCH=mips O=/kisskb/build/linus_mips-allmodconfig_mips CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/mips-linux/bin/mips-linux- oldconfig yes: standard output: Broken pipe # make -s -j 8 ARCH=mips O=/kisskb/build/linus_mips-allmodconfig_mips CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/mips-linux/bin/mips-linux- /kisskb/src/arch/mips/vdso/Makefile:61: MIPS VDSO requires binutils >= 2.25 <stdin>:1511:2: warning: #warning syscall clone3 not implemented [-Wcpp] /kisskb/src/arch/mips/vdso/Makefile:61: MIPS VDSO requires binutils >= 2.25 /kisskb/build/tmp/ccIK7Wsk.s: Assembler messages: /kisskb/build/tmp/ccIK7Wsk.s:222: Error: can't resolve `_start' {UND* section} -
