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/fe-x86-64-core-i7-2017.05/bin/x86_64-linux-gcc --version # < /opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux-ld --version # < git log --format=%s --max-count=1 0f1a7b3fac0583083ca19d4de47403511ced3521 # < make -s -j 8 ARCH=um O=/kisskb/build/linus_um-defconfig_um-x86_64 CROSS_COMPILE=/opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux- SUBARCH=x86_64 defconfig # make -s -j 8 ARCH=um O=/kisskb/build/linus_um-defconfig_um-x86_64 CROSS_COMPILE=/opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux- SUBARCH=x86_64 /kisskb/src/arch/um/os-Linux/signal.c: In function 'sig_handler_common': /kisskb/src/arch/um/os-Linux/signal.c:51:1: warning: the frame size of 2960 bytes is larger than 1024 bytes [-Wframe-larger-than=] } ^ /kisskb/src/arch/um/os-Linux/signal.c: In function 'timer_real_alarm_handler': /kisskb/src/arch/um/os-Linux/signal.c:95:1: warning: the frame size of 2960 bytes is larger than 1024 bytes [-Wframe-larger-than=] } ^ LINK linux WARNING: "rename" [vmlinux] is a static EXPORT_SYMBOL WARNING: "lseek" [vmlinux] is a static EXPORT_SYMBOL WARNING: "ftruncate64" [vmlinux] is a static EXPORT_SYMBOL WARNING: "getuid" [vmlinux] is a static EXPORT_SYMBOL WARNING: "lseek64" [vmlinux] is a static EXPORT_SYMBOL WARNING: "unlink" [vmlinux] is a static EXPORT_SYMBOL WARNING: "pwrite64" [vmlinux] is a static EXPORT_SYMBOL WARNING: "close" [vmlinux] is a static EXPORT_SYMBOL WARNING: "opendir" [vmlinux] is a static EXPORT_SYMBOL WARNING: "pread64" [vmlinux] is a static EXPORT_SYMBOL WARNING: "syscall" [vmlinux] is a static EXPORT_SYMBOL WARNING: "readdir" [vmlinux] is a static EXPORT_SYMBOL WARNING: "readdir64" [vmlinux] is a static EXPORT_SYMBOL WARNING: "futimes" [vmlinux] is a static EXPORT_SYMBOL WARNING: "__lxstat" [vmlinux] is a static EXPORT_SYMBOL WARNING: "write" [vmlinux] is a static EXPORT_SYMBOL WARNING: "closedir" [vmlinux] is a static EXPORT_SYMBOL WARNING: "__xstat" [vmlinux] is a static EXPORT_SYMBOL WARNING: "fsync" [vmlinux] is a static EXPORT_SYMBOL WARNING: "__lxstat64" [vmlinux] is a static EXPORT_SYMBOL WARNING: "__fxstat64" [vmlinux] is a static EXPORT_SYMBOL WARNING: "telldir" [vmlinux] is a static EXPORT_SYMBOL WARNING: "printf" [vmlinux] is a static EXPORT_SYMBOL WARNING: "readlink" [vmlinux] is a static EXPORT_SYMBOL WARNING: "link" [vmlinux] is a static EXPORT_SYMBOL WARNING: "rmdir" [vmlinux] is a static EXPORT_SYMBOL WARNING: "fdatasync" [vmlinux] is a static EXPORT_SYMBOL WARNING: "truncate" [vmlinux] is a static EXPORT_SYMBOL WARNING: "statfs" [vmlinux] is a static EXPORT_SYMBOL WARNING: "__errno_location" [vmlinux] is a static EXPORT_SYMBOL WARNING: "__xmknod" [vmlinux] is a static EXPORT_SYMBOL WARNING: "open64" [vmlinux] is a static EXPORT_SYMBOL WARNING: "truncate64" [vmlinux] is a static EXPORT_SYMBOL WARNING: "open" [vmlinux] is a static EXPORT_SYMBOL WARNING: "read" [vmlinux] is a static EXPORT_SYMBOL WARNING: "chown" [vmlinux] is a static EXPORT_SYMBOL WARNING: "chmod" [vmlinux] is a static EXPORT_SYMBOL WARNING: "utime" [vmlinux] is a static EXPORT_SYMBOL WARNING: "fchmod" [vmlinux] is a static EXPORT_SYMBOL WARNING: "seekdir" [vmlinux] is a static EXPORT_SYMBOL WARNING: "ioctl" [vmlinux] is a static EXPORT_SYMBOL WARNING: "dup2" [vmlinux] is a static EXPORT_SYMBOL WARNING: "statfs64" [vmlinux] is a static EXPORT_SYMBOL WARNING: "utimes" [vmlinux] is a static EXPORT_SYMBOL WARNING: "mkdir" [vmlinux] is a static EXPORT_SYMBOL WARNING: "fchown" [vmlinux] is a static EXPORT_SYMBOL WARNING: "__guard" [vmlinux] is a static EXPORT_SYMBOL WARNING: "symlink" [vmlinux] is a static EXPORT_SYMBOL WARNING: "access" [vmlinux] is a static EXPORT_SYMBOL WARNING: "__stack_smash_handler" [vmlinux] is a static EXPORT_SYMBOL Completed OK # rm -rf /kisskb/build/linus_um-defconfig_um-x86_64 # Build took: 0:00:57.370930
