ipv6: fix clang Wformat warning
When building with 'make W=1', clang warns about a mismatched format string: net/ipv6/ah6.c:710:4: error: format specifies type 'unsigned short' but the argument has type 'int' [-Werror,-Wformat] aalg_desc->uinfo.auth.icv_fullbits/8); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ include/linux/printk.h:375:34: note: expanded from macro 'pr_info' printk(KERN_INFO pr_fmt(fmt), ##__VA_ARGS__) ~~~ ^~~~~~~~~~~ net/ipv6/esp6.c:1153:5: error: format specifies type 'unsigned short' but the argument has type 'int' [-Werror,-Wformat] aalg_desc->uinfo.auth.icv_fullbits / 8); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ include/linux/printk.h:375:34: note: expanded from macro 'pr_info' printk(KERN_INFO pr_fmt(fmt), ##__VA_ARGS__) ~~~ ^~~~~~~~~~~ Here, the result of dividing a 16-bit number by a 32-bit number produces a 32-bit result, which is printed as a 16-bit integer. Change the %hu format to the normal %u, which has the same effect but avoids the warning. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Steffen Klassert <steffen.klassert@secunet.com>
