Subject: [patch v2] mtd: pxa3xx_nand: NULL dereference in pxa3xx_nand_probe
Date: Thu, 6 Jan 2011 17:05:36 +0300 [thread overview]
Message-ID: <20110106140536.GB1717@bicker> (raw)
In-Reply-To: <1294321502.2218.5.camel@sven>
"info->cmdset" gets dereferenced in __readid() so it needs to be
initialized earlier in the function. This bug was introduced in
18c81b1828f8 "mtd: pxa3xx_nand: remove the flash info in driver
structure".
