Yang Yingliang 46709163a5 pinctrl: core: fix possible memory leak in pinctrl_enable() ... commit c7892ae13e461ed20154321eb792e07ebe38f5b3 upstream. I got memory leak as follows when doing fault injection test: unreferenced object 0xffff888020a7a680 (size 64): comm "i2c-mcp23018-41", pid 23090, jiffies 4295160544 (age 8.680s) hex dump (first 32 bytes): 00 48 d3 1e 80 88 ff ff 00 1a 56 c1 ff ff ff ff .H........V..... 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ backtrace: [<0000000083c79b35>] kmem_cache_alloc_trace+0x16d/0x360 [<0000000051803c95>] pinctrl_init_controller+0x6ed/0xb70 [<0000000064346707>] pinctrl_register+0x27/0x80 [<0000000029b0e186>] devm_pinctrl_register+0x5b/0xe0 [<00000000391f5a3e>] mcp23s08_probe_one+0x968/0x118a [pinctrl_mcp23s08] [<000000006112c039>] mcp230xx_probe+0x266/0x560 [pinctrl_mcp23s08_i2c] If pinctrl_claim_hogs() fails, the 'pindesc' allocated in pinctrl_register_one_pin() need be freed.
