Arnd Bergmann 645ef9ef1f sound: autoconvert trivial BKL users to private mutex 
The usage of the BKL in the OSS sound drivers is
trivial, and each of them only locks against itself,
so it can be turned into per-driver mutexes.

This is the script that was used for the conversion:

file=$1
name=$2
if grep -q lock_kernel ${file} ; then
    if grep -q 'include.*linux.mutex.h' ${file} ; then
            sed -i '/include.*<linux\/smp_lock.h>/d' ${file}
    else
            sed -i 's/include.*<linux\/smp_lock.h>.*$/include <linux\/mutex.h>/g' ${file}
    fi
    sed -i ${file} \
        -e "/^#include.*linux.mutex.h/,$ {
                1,/^\(static\|int\|long\)/ {
                     /^\(static\|int\|long\)/istatic DEFINE_MUTEX(${name}_mutex);

} }"  \
    -e "s/\(un\)*lock_kernel\>[ ]*()/mutex_\1lock(\&${name}_mutex)/g" \
    -e '/[      ]*cycle_kernel_lock();/d'
else
    sed -i -e '/include.*\<smp_lock.h\>/d' ${file}  \
                -e '/cycle_kernel_lock()/d'
fi

README.FIRST 

The modular sound driver patches were funded by Red Hat Software 
(www.redhat.com). The sound driver here is thus a modified version of 
Hannu's code. Please bear that in mind when considering the appropriate
forums for bug reporting.
