Subject: [PATCH 5/6] MIPS: BCM47xx: nvram_getenv fix return value.
|
||||||
|
|
||||||
|
nvram_getenv should behave like cfe_getenv. For now it is used like
|
||||||
|
cfe_getenv. cfe_getenv returns 0 on success and -1 in case of an error.
|
||||||
|
Change nvram_getenv to do the same.

Subject: [PATCH 5/6] MIPS: BCM47xx: nvram_getenv fix return value.
|
||||||
|
|
||||||
|
nvram_getenv should behave like cfe_getenv. For now it is used like
|
||||||
|
cfe_getenv. cfe_getenv returns 0 on success and -1 in case of an error.
|
||||||
|
Change nvram_getenv to do the same.
