When you hit the half-way mark of the highres # multiplier, small highres movements will incorrectly translate into big # traditional wheel movements, causing odd jitters. # # Simplify the code and make the output stable. # # NOTE! I'm pretty sure this will need further tweaking. But this at # least turns a unusable mouse wheel on my Logitech MX Anywhere 2S into # a usable one. # # Cc: Jiri Kosina <jikos@kernel.org> # Cc: Harry Cutts <hcutts@chromium.org> # Cc: Benjamin Tissoires <benjamin.tissoires@redhat.com> # Cc: Peter Hutterer <peter.hutterer@who-t.net> # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/gcc-4.6.3-nolibc/arm-unknown-linux-gnueabi/bin/arm-unknown-linux-gnueabi-gcc --version # < git log --format=%s --max-count=1 044ee890286153a1aefb40cb8b6659921aecb38b # < make -s -j 8 ARCH=arm O=/kisskb/build/linus_mmp2_defconfig_arm CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/arm-unknown-linux-gnueabi/bin/arm-unknown-linux-gnueabi- mmp2_defconfig # make -s -j 8 ARCH=arm O=/kisskb/build/linus_mmp2_defconfig_arm CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/arm-unknown-linux-gnueabi/bin/arm-unknown-linux-gnueabi- /kisskb/src/kernel/printk/printk.c: In function 'devkmsg_sysctl_set_loglvl': /kisskb/src/kernel/printk/printk.c:187:16: warning: 'old' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/kernel/rcu/srcutree.c: In function 'init_srcu_struct_fields': /kisskb/src/kernel/rcu/srcutree.c:133:33: warning: 'levelspread[<Uef00>]' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/kernel/rcu/srcutree.c:100:6: note: 'levelspread[<Uef00>]' was declared here /kisskb/src/drivers/base/regmap/regmap.c: In function 'regmap_raw_read': /kisskb/src/drivers/base/regmap/regmap.c:2594:6: warning: 'ret' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/base/regmap/regmap.c: In function '_regmap_raw_write': /kisskb/src/drivers/base/regmap/regmap.c:1855:6: warning: 'ret' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c: In function 'proc_reg_open': /kisskb/src/include/linux/list.h:65:12: warning: 'pdeo' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c:341:21: note: 'pdeo' was declared here /kisskb/src/drivers/i2c/i2c-core-base.c: In function 'i2c_generic_scl_recovery': /kisskb/src/drivers/i2c/i2c-core-base.c:235:5: warning: 'ret' may be used uninitialized in this function [-Wuninitialized] Completed OK # rm -rf /kisskb/build/linus_mmp2_defconfig_arm # Build took: 0:01:18.435304
