Linus Torvalds	13509c3a9d	Merge branch 'i2c/for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux ... Pull i2c changes from Wolfram Sang: - new drivers for exynos5, bcm kona, and st micro - bigger overhauls for drivers mxs and rcar - typical driver bugfixes, cleanups, improvements - got rid of the superfluous 'driver' member in i2c_client struct This touches a few drivers in other subsystems. All acked. * 'i2c/for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux: (38 commits) i2c: bcm-kona: fix error return code in bcm_kona_i2c_probe() i2c: i2c-eg20t: do not print error message in syslog if no ACK received i2c: bcm-kona: Introduce Broadcom I2C Driver i2c: cbus-gpio: Fix device tree binding i2c: wmt: add missing clk_disable_unprepare() on error i2c: designware: add new ACPI IDs i2c: i801: Add Device IDs for Intel Wildcat Point-LP PCH i2c: exynos5: Remove incorrect clk_disable_unprepare i2c: i2c-st: Add ST I2C controller i2c: exynos5: add High Speed I2C controller driver i2c: rcar: fixup rcar type naming i2c: scmi: remove some bogus NULL checks i2c: sh_mobile & rcar: Enable the driver on all ARM platforms i2c: sh_mobile: Convert to clk_prepare/unprepare i2c: mux: gpio: use reg value for i2c_add_mux_adapter i2c: mux: gpio: use gpio_set_value_cansleep() i2c: Include linux/of.h header i2c: mxs: Fix PIO mode on i.MX23 i2c: mxs: Rework the PIO mode operation i2c: mxs: distinguish i.MX23 and i.MX28 based I2C controller ...	2013-11-18 15:50:07 -08:00
Sachin Kamat	3cd0c2dfb4	i2c: exynos5: Remove incorrect clk_disable_unprepare ... clk_disable_unprepare in remove causes an imbalance and hence gives the below crash on module remove. While at it also remove some duplicate code from probe. / $ rmmod i2c-exynos5 [ 6.996374] ------------[ cut here ]------------ [ 6.999523] WARNING: CPU: 2 PID: 1137 at drivers/clk/clk.c:842 clk_disable+0x18/0x24() [ 7.007403] Modules linked in: i2c_exynos5(-) [ 7.011747] CPU: 2 PID: 1137 Comm: rmmod Not tainted 3.12.0-next-20131105-00083-g16f4799-dirty #21 [ 7.020696] [<c0014e0c>] (unwind_backtrace+0x0/0xf4) from [<c0011784>] (show_stack+0x10/0x14) [ 7.029190] [<c0011784>] (show_stack+0x10/0x14) from [<c037acd4>] (dump_stack+0x7c/0xb0) [ 7.037255] [<c037acd4>] (dump_stack+0x7c/0xb0) from [<c001e0ac>] (warn_slowpath_common+0x6c/0x88) [ 7.046190] [<c001e0ac>] (warn_slowpath_common+0x6c/0x88) from [<c001e164>] (warn_slowpath_null+0x1c/0x24) [ 7.055818] [<c001e164>] (warn_slowpath_null+0x1c/0x24) from [<c02dcde4>] (clk_disable+0x18/0x24) [ 7.064670] [<c02dcde4>] (clk_disable+0x18/0x24) from [<bf0002d4>] (exynos5_i2c_remove+0x1c/0x34 [i2c_exynos5]) [ 7.074736] [<bf0002d4>] (exynos5_i2c_remove+0x1c/0x34 [i2c_exynos5]) from [<c02274a8>] (__device_release_driver+0x58/0xb0) [ 7.085836] [<c02274a8>] (__device_release_driver+0x58/0xb0) from [<c0227b88>] (driver_detach+0xac/0xb0) [ 7.095291] [<c0227b88>] (driver_detach+0xac/0xb0) from [<c02271c0>] (bus_remove_driver+0x4c/0xa0) [ 7.104227] [<c02271c0>] (bus_remove_driver+0x4c/0xa0) from [<c00725dc>] (SyS_delete_module+0x124/0x194) [ 7.113682] [<c00725dc>] (SyS_delete_module+0x124/0x194) from [<c000e2e0>] (ret_fast_syscall+0x0/0x30) [ 7.122957] ---[ end trace 23bb6e4e0bf52196 ]--- Signed-off-by: Sachin Kamat <sachin.kamat@linaro.org> Acked-by: Naveen Krishna Chatradhi <ch.naveen@samsung.com> Signed-off-by: Wolfram Sang <wsa@the-dreams.de>	2013-11-14 18:18:15 +01:00
