Re: [U-Boot] [U-Boot, 02/10] ext4: avoid calling ext4fs_mount() twice, which leaks

ext4_write_file() is only called from the "fs" layer, which calls both ext4fs_mount() and ext4fs_close() before/after calling ext4_write_file(). Fix ext4_write_file() not to call ext4fs_mount() again, since the mount operation malloc()s some RAM which is leaked when a second mount call over-writes the pointer to that data, if no intervening close call is made.

Applied to u-boot/master, thanks!
