Subject: perf beauty ioctl cmd: The 'fd' arg is signed
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=e1be4a5c03e1b282633e5528ea634c1cc2095c43;p=linux.git

perf beauty ioctl cmd: The 'fd' arg is signed

It is possible to pass a negative number as the fd and that has to be
handled, so stop using 'unsigned int fd' in the ioctl syscall 'cmd'
beautifier.
