From a032d33b65c89a781c871fd1def595fa6a69b52a Mon Sep 17 00:00:00 2001 From: Paul Walmsley Date: Fri, 3 Aug 2012 09:21:10 -0600 Subject: ARM: OMAP: clean up some smatch warnings, fix some printk(KERN_ERR ... Resolve the following warnings from smatch: arch/arm/mach-omap2/gpmc.c:282 gpmc_cs_set_timings() info: why not propagate 'div' from gpmc_cs_calc_divider() instead of -1? arch/arm/mach-omap2/serial.c:328 omap_serial_init_port() error: 'pdev' dereferencing possible ERR_PTR() arch/arm/mach-omap2/timer.c:213 omap2_gp_clockevent_init() Error invalid range 4096 to -1 arch/arm/mach-omap2/gpio.c:63 omap2_gpio_dev_init() warn: possible memory leak of 'pdata' arch/arm/mach-omap2/omap_hwmod.c:1478 _assert_hardreset() warn: assigning -22 to unsigned variable 'ret' arch/arm/mach-omap2/omap_hwmod.c:1487 _assert_hardreset() warn: 4294963201 is more than 255 (max '(ret)' can be) so this is always the same. arch/arm/mach-omap2/omap_hwmod.c:1545 _read_hardreset() warn: assigning -22 to unsigned variable 'ret' arch/arm/mach-omap2/omap_hwmod.c:1554 _read_hardreset() warn: 4294963201 is more than 255 (max '(ret)' can be) so this is always the same. arch/arm/mach-omap2/dpll3xxx.c:629 omap3_clkoutx2_recalc() error: we previously assumed 'pclk' could be null (see line 627) arch/arm/mach-omap2/board-n8x0.c:422 n8x0_mmc_late_init() Error invalid range 14 to 13 arch/arm/mach-omap1/leds-h2p2-debug.c:71 h2p2_dbg_leds_event() error: potentially derefencing uninitialized 'fpga'. arch/arm/plat-omap/mux.c:79 omap_cfg_reg() Error invalid range 4096 to -1 Thanks to Tony Lindgren for pointing out that BUG() can be disabled. The changes in the first version that removed the subsequent return() after BUG() states have been dropped.
