Subject: [PATCH 095/203] mtd: nand: fix memory leak in ONFI extended parameter
|
|
page
|
|
|
|
This fixes a memory leak in the ONFI support code for detecting the
|
|
required ECC levels from this commit:

mtd: get the ECC info from the Extended Parameter Page
|
|
|
|
In the success case, we never freed the 'ep' buffer.
|
|
|
|
Also, this fixes an oversight in the same commit where we (harmlessly)
|
|
freed the NULL pointer.
